Kyoniq's Aethereal Ascent

(You may cast a legendary sorcery only if you control
a legendary creature or planeswalker.)
Creatures you control get +2/+2 and gain
"Whenever this creature deals combat damage,
draw a card, then discard a card" until end of
turn. Creatures your opponents control get -2/-2
until end of turn.
