Sylblade, an Oath Kept

Equipped creature gets +5/+0 and has flying,
first strike, and trample. If the equipped creature
has any two of those keywords already, they also
gain double strike.
Whenever Sylblade, an Oath Kept would be destroyed, exile it instead, then return it
transformed at the beginning of the next endstep.
