An answer on another question tells of a way to give loyalty abilities to creatures:
Basically you start by playing the Mycosynth Lattice which turns all your permanents into artifacts, this includes Planeswalker.
Then you play March Of the Machines turning your Planeswalker into an artifact creature with power and toughness equal to it's casting cost.
Then you use the ability of an Experimental Kraj to put a +1/+1 counter on the Planeswalker artifact creature.
Now since the Planeswalker artifact Creature has a +1/+1 on it, the Experimental Kraj can use all of the Activated Abilities of the Planeswalker without any of the restrictions of a Planeswalker.
Since creatures don't have loyalty to add to or deduct from, what happens if you were to use a loyalty ability from a creature, rather than a Planeswalker?
- In the case of using a (+) loyalty ability from a creature, what happens?
- In the case of using a (-) loyalty ability from a creature, what happens?
