This makes misdirection useless by itself, as it has no way to mark enemy cards.
'Held card' means in either hand.
Thats why I used 'held ally' in the unupped, because ally implies a creature that is on your side (e.g. not creatures in the enemy hand).
So misdirection will mark cards that are in the opponent's hand as well as yours.
I have modified the card to allow direct targeting of held cards for the upped version since this still seems unclear. Hopefully it is straight forward enough now.
I also dropped the cast cost but added an activation cost for marking cards.
On a side note, this will make a very nice synergy with precognition for the upgraded version, since you would then be able to ensure that you mark a creature and not a permanent or spell when marking cards in the opponent's hand.
It could also synergy well with silence and SoBr since those could help get around players that try to counter by keeping an empty hand.
Making it a creature also allows it to self-combo, which'll either look awesome or make armadilgo fans cry.
Depends on how expensive it is, and how its stats look... hopefully I can make it awesome without overshadowing Armagio.
I think it will end up being a bit more expensive with lower HP but a more meaningful attack... More of a leader / support troop instead of a front line meat shield. So comboing on itself would be more of a last ditch effort.
Most likely it would be included as a way to enable your armagios (or maybe SoFo's) to defend your creatures instead of just the owner.
The amusing thing now that I think about it, is that the unupped version (which needs ) actually works better with dolls than the upped version which uses
I added a note in the OP. This effect only triggers 1 time per copy of this card you own. E.g. to stop 3 damage sources in a turn, you would need 3 of these cards in play. This will help keep it from overshadowing the gravity pull mechanic which is not limited in this way.
For the purpose of this limitation, mass target spells are treated as a single 'source' so all the damage would get intercpeted / misdirected.
