Bolas's Hydra

When this creature enters the Deathtouch
battlefield, Hydra creatures you Reach
control gain Trample until end Trample
of turn. Draw a card equal to
the amount of Hydras you control.
At the beggining of your upkeep, gain life
equal to the amount of Hydras under your
control. If you have three or more, each creature
you control gains Deathtouch until your
next upkeep.
