Icehide Troll

The plain 2/3 body is doing exactly what the design intends: it exists to hang a mana sink off of, and every interesting decision this card makes lives in that double-snow activation. Paying two snow buys +2/+0 and indestructibility until end of turn, and the tap is baked into the effect rather than charged as a cost, so nothing gates you to a single activation per turn. Because the ability taps the creature on resolution, the timing runs the other way from what you might expect: fire it before combat and you tap your would-be attacker out of the fight entirely. The window that matters is after attackers are declared, once tapping no longer removes the creature from combat or cancels its damage. There the ability guards an attacker already committed, and it guards a blocker just as readily. The protection is also pointed: indestructibility answers the two deaths green creatures suffer most (burn to the toughness and outright destruction), yet it is silent against everything that routes around the battlefield. Exile, bounce, and edict effects all sidestep it, since being told to sacrifice is not being destroyed. And the payoff stays patient rather than explosive. The +2/+0 does nothing to force damage through, so a chump blocker still stalls it, and no single activation closes a game. What a snow-heavy shell gets is a conversion engine: the same permanents that cast your spells become fuel to turn flooded draws into a grind of harder-hitting, harder-to-remove attacks.
