I’m missing how this is a turn 3 win that will be worthy of a banning for a card.
Turn 2 you have two lands, two Noble Hierarchs, and a Strangleroot Geist out. The 2/1 geist can attack thanks to its haste, and it attacks alone, so it becomes a 4/3 from the two exalted Hierarchs. That’s 4 damage.
Turn 3 you play another land, and with your three lands and two Hierarchs cast Finest Hour. Now when the geist attacks it gets +3/+3, becoming 5/4, and deals 5 damage. That’s 9 total. Finest Hour untaps it and allows you to attack again, and you do so gleefully. All of the exalted abilities trigger again, giving another +3/+3, and the geist is now an 8/7, and deals 8 damage. That’s 17 total.
Then you have Gut Shot there, and since 3 damage must be done to win on turn 3, I’m guessing you’re saying to cast three of those.
To win on turn 3 then, you need 3 land, 2 Noble Hierarch, 1 Strangleroot Geist, 1 Finest Hour, and 3 Gut Shot. That’s 10 cards, and assuming you don’t mulligan you will have 10 cards on turn 3 if you’re on the draw and not the play.
This is a perfect example of Magical Christmasland thinking. You need exactly those 10 cards, so there is no room for error, and no room for tutors or draw spells to ensure the deck plays out with any consistency. If it could play with any sort of consistency, you certainly do have a strong deck, but not one anywhere near consistent enough to warrant the consideration of a card for banning.
Of course, maybe I’ll be proven wrong. But only time will tell. Until then, you’re talking about the possible banning of a card that hasn’t even been released yet. If that’s not jumping the gun on that discussion, I don’t know what is. Just like with players talking about hating drafting with double-faced cards months ago, why don’t we wait to play with them before we start making such big conclusions?
