Hivemind Aggressor

When Hivemind Aggressor enters the battlefield,
look at target players hand and choose a creature
card from it. Exile that card. You may play cards exiled with Hivemind Aggressor from exile, and
you may spend mana as though it was mana of
any color to do so.
Creatures played this way are tulkari in addition
to their other types.
All will join the hivemind in time.
