I sat for a long time staring at the words "HP is always 1" before I decided to go with it. It's tricky.
So: Crane's HP is
always 1. What this means is that Crane can attack a Fire Shield and not take damage. Its HP will "always be 1." RoF and Thunderstorm would not affect it. Plate Armor would not give the Crane a bonus to HP either. It's HP will - say it with me - always remain at 1. No buffs. Immaterial still open to Petrify, Freeze, Devour (etc) in other words.
Now for where the confusion comes in (deep breath): I screwed up. Sorry. I didn't do the research before finalizing the card. After going through what is already in the game, I've compiled a short list of possible ways this creature's stats could be affected (Sky Blitz, Rage, Chaos Power, Holy Flash, etc) and realized - there
are no cards in Elements that boost only attack, outside of the aforementioned Sky Blitz & Rage (and mutation). Well then, that changes things. Let's forget the second half of the card's text for a moment, shall we? What does the leave us with?
Gravity Pull. If this creature can't take damage, and GP gets tossed on it...well, that's an uber-wall that can only be devoured. Is this OP?
Now, the alternative, in my mind, is to open up the Crane to damage. State clearly that this creature's HP will always remain at 1 and it
can take damage. It is, after all, only paper. But ew. What's the good of it, other than a quanta-generator when upgraded? Of course, the text could be removed altogether, leaving it as a 1|1 Airborne. It is meant to be Vanilla or close-to.
Finally,
kinda on the same lines here!
I think the tricky thing is to know when the crane loses 0HP and gets back to 1.
For example, could it survive attacking Fire Shield?
I'm not sure I understand, but perhaps "Paper Crane's HP is always 1." is all you need? Or is it the case that it 'dies' when buffed, then comes back with 1HP to stop this (kinda immaterial) creature gain endless attack with blessing etc?
I like this idea. Hm. It would fit with Schrodinger's Kitty and activate Death effects.
Sorry for all the confusion, peoples. I'll be sure to be clearer in the future. In the meantime...suggestions?
