Scarrd, Dragon Warleader

Flying, trample, haste
All dragons you control get +1/+0 and have
"{r}: This creature gets +1/+0 until end of turn."
At the beginning of your upkeep, you may
search your library for a dragon permanent card
and put it onto the battlefield. If you search
your library in this way, shuffle it. It gains
haste and is sacrificed at end of turn unless you
pay its mana cost.
