Heldegar

This character gains +1 Attack and +1 Defense for each Spell Action you cast during combat, until end of combat.

At your Remember step, you may Sacrifice any number of other Characters you control. If you do, return a number of Spell Actions from your Remnant Field to your hand equal to the number of Characters Sacrificed this way, where each returned Spell's Memory Cost does not exceed the Memory Cost of the Character sacrificed for it.

The first time each turn a Character, Artifact, or Shard you control enters or exits your Remnant Field, draw a card.
