Archdruid's Charm

The whole point of a modal card is that each mode covers a matchup the others cannot, and this one is unusually clean about it: ramp-and-fetch for the ground you cannot beat on the ground, a one-way bite for creatures you can, and hard artifact-enchantment removal for the permanents green normally has to route around. That third mode is the tell. Green's traditional answer to an artifact or enchantment has always been a Naturalize-style destruction spell, which enchantments have learned to shrug off with indestructibility or recursion; exile is the color's structural weakness patched at instant speed, in a slot that also happens to fix your mana or grow a threat. The triple-green cost is what pays for the flexibility: this is not a splash, it is a card that demands you commit to green as your primary color, and in exchange it collapses three different green cards into one. The second mode deserves attention too, because it stacks the counter before the damage, so a 2/2 with the counter deals three, not two: the pump feeds the bite in the same resolution, and because only your creature deals damage, you keep the growth without taking a swing back. What holds it together is that no single mode is a bomb; the value is entirely in never drawing the wrong half of a two-card answer.
