Fulgur, the Bolt-Furred

Trample, Haste
Ritual Casting: {r} (Whenever you cast this creature from thecommand zone, you may pay {r} for each time you've cast it from your command zone beyond the first. If you do, for each {r} that was paid this way, reduce the mana cost by {2}.)
Whenever an instant or sorcery you control would deal damage to a player, Fulger gets +2/+0 until end of turn.
At the beginning of your end step, if Fulgur was ritual cast, sacrifice it.
