I personally think you should change the Tails effect, because it is essentially cancelling itself out. You get TAILS, then its effect is automatically switched to Heads.

Change it, then it won't be as broken.

That was the point.

Very nice card which fits the archetype pretty well in flavour and effect. Nice.

Maybe add 'This card is also treated as DARK?'
