1) Would a permanent that lets you discard costs to increase your hp or gain quanta (like half of the discarded card) be good?
2) Do some shards fit too much of a niche instead of being able to be splashable like they were meant to?
3) Would something like this be a good idea? As a spell? If the difference was changed to +/- 4?
4) Would a permanent that stopped all spells for both people for 3 turns be a good idea? What would be the cost?
5) Besides the shards, are there any cards that you feel to be OP?
6) Did you ever try this logic game? It's quite fun.
1)
The cost of the discarded card is not paid. It should not impact the benefit gained. Otherwise yes.
2)
Yes. Shard of Wisdom cannot be used without
or
. Shard of Focus is too powerful for a splashable card (Hence cannot be simultaneously balanced for rainbows and mono decks without a major change). Shard of Sacrifice has a disloyalty penalty rather than a loyalty bonus.
3)
It can be used both as Attack Reduction and Rage. However Attack Reduction can be accomplished by CC (prevent attacking or remove the creature) and Rage is already a spell.
So no. I do not think it is a good idea
in addition to cards already in the game.
4)
A rush deck would love that card since it prevents the opponent from equalizing. 3 of those would be 9 turns of status quo. (with 3 turns of playing between the double sided Silence) I would reduce it to 2 turns and a cost of 4 quanta.
5)
Yes. The degree of imbalance differs from card to card. I find cards that have imbalance less than 1 quanta in magnitude to be balanced. I consider cards with imbalance of more than 1 quanta in magnitude to be overpowered. This ranges from cards that are slightly to cheap (Fog, Graboid, Reverse Time) to metagame injury (Shard of Focus). However I have watched the card pool get fine tuned. Most of the op cards are now in the slightly too cheap bucket.
6)
Yes. It is quite fun.
