Well, I wanted to make a merger of Furnace Drake(which just flat out Exiles all Artifacts once you play it from your hand, making it a worse offender for the Affinity issue) and Hellkite Overlord. The two cards linked in the name... The reason for being from the field is that it's instant speed and thus can be used as a pseudo-Regenerate, borrowing from Hellkite Overlord. The Bounce clears a good number more threats from it, but then you have to recast it, rather probably with less Affinity credit.
Although there's shenanigans to be had with some readings of interactions with stuff like Artifact Mutation or Death Mutation, where the effect after the destruction doesn't require the creature to still be there. And because it's not Regenerate, it successfully recovers the card.
As for Root Strength, it makes sense and requiring Basic lands solves one of the major issues with any such card in Legacy. Namely, Life and Limb, which doesn't cause Saprolings to be Basic Lands. So it's good in Landfall, and can work as a debuff for particularly large creatures alongside heavy land destruction or enemy early power plays(like Slivers using ramp to get out Legendaries with only two or three lands), but a lot of the things that could make it problematic are left out by the basic land clause.
Without any real exploits making it more powerful as a buff, it's a good scaling effect that's a useful buff in Landfall deck, or land-focused ramp decks. Normally, it'll not make a really strong creature until after most games are already over. Nice and balanced because it's only useful in edge cases, as far as tournaments go, but you can build decks around those edge cases. It'll never be the core of a deck, which is good. It's a superstar pick for land-based ramp decks, but it isn't going to be the win condition of the deck.

That's a pretty interesting winmore card, as it's extremely cheap but you have to have the opponent pretty close to death already. I'd actually make it cost , because you have much less ability to control the opponent's life total than you do your own. Death's Shadow is a good card because it's an excellent finisher for Suicide Black, which can reliably get themselves down to a small enough amount of life to get a 5/5 or more out of it. Reliably getting the opponent down to 11 life without enough blockers to stop this is pretty hard, especially because the Red inclusions useful to get Death's Shadow some Haste for your finisher become much more complicated when you need to have White mana.
Overall, it's kinda a bad place for card design, because it's only useful to finish off the opponent when you're already pretty close to doing so. Death's Shadow is largely useful because it slots in well with a deck type that can afford to have a win condition reliant on having less than five health, because it can reliably get to that when desired.

This is a pretty strong card, to the point where I think it should cost 2 mana to activate the ability. The thing is that it eats a drawn card in a similar way to forced discard, although the requirement of having more than four creatures might balance that out. In terms of what it actually accomplishes, it's like conditional but costless Unsummon, with the condition being severe enough that it makes up for effectively having mill power and shutting down Flash(which opens up some viable targets/situations that make it work against some otherwise-problematic archetypes, like Slivers, who have tribe-wide Flash access and the mana generation to resummon with ease)

This kinda needs some clarification about the effect, and the point of it being Fights, instead of dealing damage, is that the creatures are dealing damage. So stuff like Lifelink and Deathtouch kick in. The Morbid effect makes it so that you can have a creature that's already dead be targeted for recovery or to Unsummon an enemy while getting Lifelink damage in. Fights is found mostly on Red cards, but also on a couple Green cards and Green is where more archers are at(as well as having the revival access), and most uses of it are 2 or 3 mana cost, while the "return to hand" effect is one mana on a Common.
...It should probably cost one or two more mana than the initial version, honestly, given that there's some ETB abilities which get nasty when you can repeat them.

Being in red is a vital limiter, as there's very few decks with large Red inclusion that also have the life gain to make this a problem. Elf decks are the big thing to worry about, particularly with an Eldrazi titan present to reshuffle the graveyard. But this is getting to self-mill combos and multi-Mythic strategies, so it's mostly just a way to get out of the dreadful topdeck situation at the cost of some life. And, as mentioned, it can kill the enemy by making them hit themselves with a big creature. It can also mill them if they survive.

Huh. At first, I thought you forgot Lifelink was a thing, but the damage prevention causes Lifelink to fail to function. It's a rare case of an Aura that can be useful when applied to an enemy creature, even though the effect is intended to be friendly-only. This is because you can stick in on an enemy as a discounted Pacifism with the "cost" of your opponent gaining health whenever it would normally deal damage. Hundred-Handed One is a good target, as it can block a usually-practically-infinite(Really only Elves and Slivers reliably get over 100 creatures) number of enemies and doesn't need to deal damage to be useful as a blocker.
That's... An interesting implementation of a transformation effect. It's a great way to clear out -1/-1 counters from really big hitters and resetting high-end Clockworks, like Clockwork Hydra. For creatures that come into play with numerous counters, it lets you generate massive numbers of Insect tokens fairly rapidly. But the cards able to make this problematically efficient are very rare. Clockwork Dragon gives you a net gain of five tokens for five mana, which is fairly reasonable. Resetting it takes other creatures to generate tokens, but is still not causing a huge amount of trouble.
The most problematic feature of this, I suppose, is that it renders those high-efficiency "cyclers" utterly unremovable, and keeping two mana free to recover them at the last moment is not a huge penalty. But this isn't actually problematic outside of a rare few absurdly high counter density creatures. I mean, it's also unlimited use flickering, but at five mana a pop and being shut down by field damage instants, it isn't effective enough to be problematic in its capacity to remove targets in the middle of targeting.
I mean, Doubling Season, as usual, utterly destroys the balance of the card, but if we judged by combo potential with inherently massively broken cards, we'd never see anything remotely interesting as balanced. A partial solution to that is using Phasing instead of Exile, which at least cuts off doubling ETB counters, but using archaic mechanics that were always overcomplicated to work around overpowered cards that render so many other cards broken combo pieces is, again, not exactly productive.
