If you folks really wish for a change of name, I'd suggest "tresor", "Spoils of War" or "Greed".
Though "Greed" would rather be a spell with the same effect.
IMO Bank is absolutely fine though.
As for a minor side effect, I already thought about that, here are a couple of ideas:
"Thieves Guild" - Same as Bank, but does 1 damage to a random opponents target each turn. (creatures or opponent).
"Bank" - If your Quanta would be stolen, 50% chance to be not stolen (not stackable)
"Spoils of War" - Whenever you kill an opponents creature, gain 1 Electrum.
- Whenever a creature dies, spawn a 0/1 restless spirit (no abilities)
"Tresor" - If you lose the match, gain back your lost Electurm. (pretty much useless though, does not stack!)
Well in the end I chose the version without additional skill. This is only there to help you with farming, or to show your opponent in PvP how much more supperior you are at deckbuilding, if you play a bank and then win xD
(a relic just doesn't kick it, since you can't play it
)
