Kabold Half-Dragonettes

Twinstrike — Whenever Kabold Half-
Dragonettes attacks, all creatures you control get
+1/+0 until end of turn. After this creature does
its combat damage, it deals its combat damage a
gain at the beginning of your endstep.
"These are bred through different passages, some dangerous, some great and playful. Just the fire you
might have to be careful with."
