Whenever two or more creatures you control deal combat damage to a player, you lose 1 life and draw a card.

When Whistling Blades enters, you may destroy target creature or planeswalker.

Alpha (You may have this creature enter with a +1/+1 counter on it. If you do, it becomes alpha and can only attack alone.)

You may exert Wiedfree Berserker as it attacks. When you do, target creature can't block this turn. (An exerted creature won't untap during your next untap step.)
If exerting a creature you control causes a triggered ability of a permanent you control to trigger, that ability triggers another time.

You may put a creature or planeswalker card from your hand onto the battlefield. It gains haste. Sacrifice it at the beginning of the next end step. Whenever an ability of that permanent is activated this turn, you may copy that ability. You may choose new targets for the copy.

Whenever a creature blocks Wildborn Courtesan, draw a card.
{R}{R}: Untap target creature an opponent controls. That creature blocks Wildborn Courtesan this turn if able.

When Wildborn Merchant enters, each player discards their hand, then draws X cards, where X is the number of Nobles you control.

When Wildsong Summoner enters, shuffle your library, then reveal cards from the top until you reveal a permanent card. Create a token that's a copy of that card, except it's a 3/3 green Beast creature. Put all cards revealed this way on the bottom of your library in a random order.
