El Galgo, Dashing Troubadour

Companion — Your starting deck contains only
red and white cards, and land cards.
(If this card is your chosen companion, you may cast
it once from outside the game.)
When you cast your first red spell each turn, gain control of target creature an opponent controls,
untap it, and give it Haste until end of turn.
When you cast your first white spell each turn,
you may exile target nonland permanent,
then return it under it's owner's control.
