MTG Salvation

Seems insane in Limited, 2 mana poking flier with defensive stats and strong mana sinks late. No idea if it'll see Standard play, doubtful though I imagine. Mostly a really strong Limited card.

Honorable Mention: Roccovsky (This is a pretty cool card, but something feels off, I can't fully place my finger on it. Might be the lopsided mana.), atogstorm (Feels like a card that should exist already but the top 2 were hard to crack into.)

Honorable Samurai 2WW
Creature - Human Samurai (R)
Bushido 1 (Whenever this creature blocks or becomes blocked, it gets +1/+1 until end of turn.)
Whenever Honorable Samurai attacks alone, it gains Bushido 1 again for each other attacking creature you control.
It is only in single combat that virtue shines.
3/3

@ Flatline: Just for one last thing, one reason cycling itself is way better than Sphinx of Magosi (IMO) is that you can always just cycle it for a card if you don't get the combo going, need to smooth out early or so on. Sphinx of Magosi has a good chance of being a dead card in your hand with its 6 CMC and no way to use it except playing it, but you can always just ditch Infinity Sphinx for a card at the very low price of U, so it takes away one of the notable downsides of Sphinx of Magosi, which is putting a 6 CMC card in your deck that won't necessarily win when dropped and can be a very dead card. A U cycle card is always useful as a filter for very cheap. Reliability can be a pretty big thing for a card's power level.

And then it can do the cheaper cycle draw AND combo with stuff like Wild Mongrel, as well.

Jungle Giant 3GGG
Creature - Giant (R)
Whenever you summon a creature with 5 or more power, draw a card.
Whenever you summon a creature with 4 or less power, place five +1/+1 counters on it.
6/6
To the strong, an equal. To the weak, a protector.

@ Flatline on Infinity Sphinx: I was mostly just worried about the combo with itself, because the cycle is only one blue mana. Not only is it pretty strong with itself, an extra draw each turn for 1U essentially, but it also has strong and cheap synergy with any cards that take advantage of cycling, on a fairly big flying beater in the best color to protect it.

I was also somewhat worried by the fact that it might not have enough big downside with only a U cycling cost. It not only puts itself into the GY really good for recursion, which could potentially allow silly cycling stuff, but you can basically always ditch it for a card if you have to, making it kind of low risk. I felt like either the cycling or recursion effect should have cost slightly more, probably the cycling cost, and then maybe bring its actual mana cost down by 1 or U? Make it a bit more consistant to get out but lower the top end power.

I should note that I'm not the biggest MTG player here so my balance thoughts are probably not the best.

Honor Among Thieves [mana]1WU/mana]
Enchantment (R)
Thief creatures you control have Bushido 1 (Whenever this creature blocks or becomes blocked, it gets +1/+1 until end of turn.)
Whenever a Thief you control deals combat damage to your opponent, you may draw one card, then discard one card.
Even without trust, a silent code prevails.

You said thief as a creature type, so making a support card for them is allowed, right?

IIW: A card with only colored mana used to cast it, and at least two mana.

Call of the Clergy 2WW
Enchantment (R)
Clerics you control have Lifelink.
Whenever a Cleric deals combat damage to your opponent, place a +1/+1 counter on it.

(The Vizier and his tokens are clerics, so they get buffed, and they can't be blocked so it procs easier!)

5/5

Lightshire Protector 3WW
Creature - Human Knight (R)
Protector (When this creature enters the battlefield, you may pair it with another creature you control. If you do, this card gains power and toughness equal to the paired card, all of its abilities, the paired creature has Hexproof and cannot attack or block.)
While Lightshire Protector has 6 or more toughness, it gains indestructable and can block any number of creatures during each combat phase.
1/3

This wording is probably dumb, but I got an idea so whatever.

IIW: Make a legendary creature OR a Planeswalker that costs 2 or less mana.

I got a vote from entombedhydra on April 13th. I know it won't matter much in the end, but could it be recorded on the leaderboard?

EDIT: Thank you!

I should seriously try to come here more often...

Landsoul was me randomly thinking about mechanics to work well with my old Monochromatic mechanic, the idea being it counts either basic lands or non-basic lands, with the basic lands working well with monochromatic. Feel like it could be cleaner or better done, but oh well.
