Genghis Mons

Genghis Mons gets +1/+1 for each non-token
goblin you control, and has shroud.
Attacking goblins gain +1/-1 and trample until
end of turn.
When Genghis Mons attacks for the first time
each turn, gain control of all Goblins and untap
them. After this phase, there is an additional
combat phase.
