Bah, Sheena attachment issues

I'm for a constant attack of zero.

I'm not going to comment on whatever because it's already been said and nobody'd read it at this point anyway.

Edit: No, actually, I will, but briefly.

There's a difference between the flavour for a character and the flavour of a card (its designed function/purpose). This has been said in more detail already, so I won't go into detail again.

Also, that flavour aside, 575 and two cards and a life maintenance for a 50/51 that can't be targeted by mods, spells or abilities and takes no combat damage. The problem here is that this is far too powerful. This is even before considering that you can transform her into a 110/4 lifebar monster (hooray for constant attack), and gamble on a transformation back (to a 50/1) which could wipe out all the opponent's non-unique monsters.

Constant attack of zero isn't the only option. Being unable to attack/defend is an option. Raising the mana costs of either or both cards is an option. Reducing the statgain of Shadowforce Heart is an option. There are probably quite a few other very simple options. But each of these weaken the individual cards outside of the combo. Constant attack of zero weakens the combo, while affecting only a very select few other combos. But for the most part, I can use Sheena without the constant attack of zero being a problem, and it doesn't change Shadowforce Heart at all. It pretty much just removes the problem, and it fits the card's (presumed) original purpose.

That it seems to be in flavour with the webcomic character is an added bonus.
