Minor Spell • Cost: 1
One of your tech 0 or I units becomes a copy of another tech 0 or I unit until end of turn.
Copying something copies the printed version of the card and does not copy any modifiers. For example, if you copy a 2/2 that has a +1/+1 rune on it and Spirit of the Panda attached to it, the copy will just be a 2/2. — Sirlin, 03/07/16
If an effect changes the "printed" values of a card, the new values will be used. This includes Chaos Mirror and transformation effects such as Polymorph: Squirrel., 03/27/16
