Expensive Upgrade: Solphim, Mayhem Dominus Sure, Valgavoth is more about life loss than damage specifically, but there are lots of damaging cards in this group slug deck, and Solphim, Mayhem Dominus is going to make them all work so much harder
A better fit for this card would be artifact-heavy stax lists such as Heliod, Sun-Crowned , especially if they run cards such as Mishra's Workshop that can help get Trinisphere out early to start putting pressure on the faster decks at the table
(Regular Art Card found in 30% of packs Foil-stamped Signature Art Card in 5%.)
This is a five-mana white enchantment that reads: If one or more creature tokens would be created under your control, that many 4/4 white Angel creature tokens with Flying and Vigilance are created instead. Basically, if you were going to make a 1/1 Goblin token, for example, you would instead make a 4/4 angel with Flying and Vigilance
This list has plenty of colorless and high-cost creatures that you can play basically (sometimes entirely!) for free
