I also think that unless people are explicitly making personal attacks that no one is judging you as a person for running or not running any given card. And if someone is making those kind of attacks, I'll certainly report them. I'd rather people with a minority opinion speak up to give their point of view than feel shunned.
Given that there are only three blue cards with threshold (four if you count Cephalid Coliseum), I'm assuming that it's really more of a self-mill archetype than just that mechanic in particular.
Seer's Lantern, Unstable Obelisk, and Pristine Talisman all serve similar functions and how they rank is going to fluctuate based on your deck and likely matchups. You're right that none of them are great if you have CMC2 mana rocks, but a lot of us are moving away from generic turn two ramp effects in order to curate our cube metagames.
I don't mind portal or shard from a pure power level standpoint, but I've ended up abandoning them just because they lead to repetitive gamestates when they are working. Keep shard up to make opponent keep mana up on their turn, then EOT bounce your best ETB guy to replay it on your turn is fun the first couple times, but got old (especially on the opponent's side) pretty quickly for us. It's more a matter of taste than anything.
Keep in mind that animating a land with Wall of Resurgence is a "may" ability. I think making the 3/3 when you cast it on curve is probably the wrong decision a lot of the time, but a 0/6 wall that can also turn an extra land into a relevant body in the late game is playable in control.
Whether Snapcaster is broken or not really depends on the density of good cheap instants and sorceries in your cube. If you don't run cards like Lightning Bolt, Path/Swords, or Serum Visions/Ponder/Preordain, it's a much more fair card.
I disagree. I think in the game of Magic you should always be prepared for something to happen, even if your opponent is tapped out.
Okay, but that's a preference of taste, not an objective rule of the game. Again, I'm not personally against free spells existing or even being cubed, they're just not for me. If you like it, go nuts and enjoy! That's the beauty of cube, everyone can build to their own preferences.
I think it's very reasonable to suggest that instant speed spells that can be played for zero mana are different from other tricks. Being able for new players to see their opponent being tapped out as a green light is a good thing, in my opinion. If you play with experienced people or a regular group that's totally cool, but not everyone has that situation.
Exalted Angel would be fine in most peasant cubes because there is so much spot removal. I think it's weaker than Cloudgoat Ranger, for example. It is unlikely to see a reprint in Standard because it breaks the 5-mana rule set in Khans for whether a turned up morph trades/bounces or kills an opposing 2/2 creature. And they don't usually do rarity shifts in supplemental products.
Unless there's one that comes alphabetically after Walker of the Wastes, we've seen all the true colorless creatures from the set. If there's going to be anything using C that's cubeable, it will probably have to be an activated or triggered ability from a colored card.
That's probably true, in which case the odds of colorless being worthwhile are pretty low. It makes sense considering we have over 20 years of cards for the other colors and basically just a single set for colorless. Maybe in Return to the Battle for Zendikar we'll have the critical mass needed, heh.
There's already the Duel Decks: Elspeth vs. Tezz version out there for that, just FYI.
