Marisa, Proud Gladiator

Gift a free shot (You may promise an opponent a gift
as you cast this spell. If you do, until your next turn,
creatures you control can't attack that opponent or
block creatures they control)
When this creature enters, if the gift was promised,
create a 3/1 white Cat creature token.

At the beginning of combat on your turn, choose
haste, trample or vigilance. Creatures you control
with power 3 or greater gain the chosen ability until
end of turn.
