The problem I find with this card is that you MUST have to play it, which takes out the whole most-decks-can-use-it thing. Maybe allow it to buff any creature, but only quinted creatures getspell damage and +4 while any non-quinted creatures simply get +2?
Actually I like your idea. It could see use in decks that want to use doubling cards (like PU, Deja Vu or Dive-creatures), but without a second element.
Hmmm... I haven't thought about that, but what I really want is to make usage not strictly necessary.
How about use on a non-quint creature only gives it spell damage? Without the +4 atk
No. Momentum would be useless.
Actually, I think it's a good idea for the following reasons:
-it's called Shard of Wisdom, and spell damage is more appropriate to the wisdom theme than the buff.
-more decks using spell damage will rise (it would increase the meta)
-and so it would buff reflecting shields, increasing its use.
-momentum would still be more powerful, since it cannot be reflected, only lobotomized. Also, shard of wisdom costs 3|1
, momentum costs 2|1
. Since SoW wouldn't grant a buff for non-quinted creatures (while momentum always give a buff), momentum still maintain its use. It's better when you have access to gravity quanta and don't use immortal/quinted creatures.
