I still wanted to find a more automated way to design custom cards
These include Siege Rhino (drain), Skirmish Rhino (drain), Workshop Warchief (life gain), Charming Prince (scry/life gain/blink), Satyr Wayfinder (land fetch), Ravenous Chupacabra (removal), Eternal Witness (return card from graveyard) The deck then adds numerous blink spells and effects including Yorion (blinks your whole team!), Charming Prince, Restoration Angel, Touch the Spirit Realm, Acrobatic Maneuver, and Cloudshift
Turns out I love me an alternate cost flashback card
It exiles up to one target nonland permanent that you control and returns it to the battlefield under its owners control
