Spellbreaker Behemoth

Built for the player who hated drawing into a wall of blue, this is hate stapled to a beater rather than spent as a dead card. The body that brings the threat (a 5/5 for four) is also the qualifier for the protection: it both meets the power-5 bar itself and uncountable on the way down, so the first thing it does is resolve regardless of what is held up. Everything after that is the more interesting clause. Most anti-counter cards protect themselves and nothing else; this one extends the umbrella to a whole class of your creatures, the fatties, the exact spells a control deck most wants to answer on the stack. That turns the relationship between a stompy deck and a permission deck on a single axis: the counter-magic does not get to interact with your largest threats at all, so the control player is pushed off the stack and onto removal, which a green-red creature deck is far better equipped to grind through. The restriction is what keeps it fair. The protection only covers power 5 or greater, so your mana dorks, your early creatures, and your noncreature spells all stay vulnerable; you have to actually be casting giants for the second line to mean anything. It is a narrow lockpick that only works if your deck is already shaped like a battering ram.
