Ydiri and Shu, Inseparable

Whenever an opponent casts a spell, if it isn't the
first spell that player cast this turn, until end of
turn, creatures that opponent controls can't attack
you or a planeswalker you control unless that
opponent pays {1} for each attacking creature.
Whenever you cast your second spell of each turn,
draw a card.
