Geonosian Arena

When Geonosian Arena enters the battlefield,
enchant target basic land you control. Then
choose three target creatures an opponent
controls and put an arena counter on them.
Creatures with arena counters cannot attack or
block and do not activate abilities. If you
control three beast creatures, deal 3 damage to
each opponent at the beginning of your end step.
{2}{w}{u}{b}: Search your library for a beast
creature and put it onto the battlefield tapped.
