Noxious Hydra

Kicker {b/g}

Whenever Noxious Hydra takes damage, add a
+{x}/+0 counter to it, where {x} is the amount of
damage it took. If it was kicked, instead add
+{x}/+{x}. Remove it at the end of your next turn.

Landfall (Whenever a land enters the battlefield
under your control, Noxious Hydra gets +0/+1
until end of turn.)
