guzma pokemon card full art Cosmic Eclipse & Hala #229 Shiny Vault Type PSA10] Guzma PROMO 396/SM-P Extra

Prototype isnt an activated ability but a static ability that provides a different possible casting cost for your creature

She buffs the team and enables you to constantly be gaining life, triggering your Resplendent Angel and Angelic Accord, and is just a very powerful body on her own as a 5/5 body with flying, first strike and lifelink

700 double serialized foil Dwarven Sol Rings

This is really more of a Commander alternate win-con since you begin only ten life from winning

For Incubator tokens, this won't include any +1/+1 counters, so this may result in the creature immediately dying

It should be ok, even though the exile cost is a little steep
