The Siren and the Screamer

Flying, haste
At the beginning of combat on your turn, for each Dragon you control, gain control of target creature defending player controls with lesser power until
end of turn. Untap that creature. It gains haste
until end of turn.
Whenever a Human you control attacks, it deals 2 damage to defending player or planeswalker. If you
don't own that creature, draw a card.
