First strike
At the beginning of each end step, if an opponent has more cards in hand than you, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)

Whenever you scry, put a +1/+1 counter on each of up to X target creatures, where X is the number of cards looked at while scrying this way.
Whenever a creature you control with a +1/+1 counter on it becomes the target of a spell or ability an opponent controls, you may draw a card.

If a creature an opponent controls would die, exile it instead.
+2: Up to one target creature gets -4/-1 until your next turn.
−2: Each player sacrifices a creature of their choice. If you sacrificed a creature this way, create a 4/4 green Beast creature token with trample.
