Considering all these three cards need five Ink to be played, having Hamm, Piggy Bank in play can be quite handy and it can be exerted in order to pay one Ink less for the next Character that is played
Getting to repeatedly pinpoint wraths gives this card a lot of potential
For example, I didnt even mention the puzzle piece cards that could be assembled to build a super-oversized Chaos Orb (the majority of value to these lies in the one ultrarare piece, see image below)
Then when she ETBs, you make two 1/1 Thopters with flying that are artifacts
Cards such as Swords to Plowshares , Abrade , and Natures Claim are considered staples for a reason
Mother of Runes is a repeatable, tricky card that can be tough to work around
