Choose up to two target creatures you
don't control. For each of those creatures,
create a token that's a copy of that
creature. Those tokens gain haste. Exile
them at the beginning of the next end
step.
"But, use this, to summon one another as spirits,
cross the gaps between the worlds, and engage in
jolly co-operation!" — Solaire of Astora
