Jubal, Master of the Hunt

Vigilance, first strike, haste
Whenever a creature you control attacks, you may discard a card. If you do,
you draw a card
Creatures that entered the battlefield under your control this turn get +2/+0,
haste, trample and menace until end of turn
Deadly Speed: when Jubal enters the battlefield, target creature gets double strike,
trample, menace and haste until end of turn
