Sobekon, God of the Desert

Trample, hexproof
At the beginning of combat on your turn, if another creature with power four or greater entered the battlefield under your control this turn, creatures you control with power four or greater become Crocodiles in addition to their other types until end of turn.
Crocodiles you control get +2/+2 and have trample.
Sobekon grants strength to those who defy.
