Jacc, Zhur-Taa Aspirant

Riot.
You may tap four creatures you control with
power or toughness of 1 or less instead of paying
Jacc, Zhur-Taa Aspirant's mana cost.
When Jacc-Zhur-Taa Aspirant enters the
battlefield, other creatures you control have haste
until end of turn and you may put a +1/+1
counter on all tapped creatures you control.
