Nero, King of Tarkir

Trample, first strike, vigilance
Whenever Nero attacks, choose one:
• creatures you control gain vigilance and trample until end
of turn.
• X target creatures you control gain indestructible until
end of turn where X is half the number of creatures you control (if half is uneven, round up.)
then destroy X target creatures.
