There are tons of ways to get counters on creatures so Volrath can turn into them, but my favorite is Tetzimoc, Primal Death, which can repeatedly put a prey counter on any creature for just one black mana
You just have to really carefully judge how many colorless mana you can afford to have in a deck
Whether you revel in it or despise it is irrelevant, the strategy persists all the same these are the stax-locked games
Honorable Mentions: Gisela, Blade of Goldnight While technically not a double striker, Gisela, Blade of Goldnight deals damage in double thanks to its own ability, and it also extends its ability to all your other damage sources
Foil effects are especially popular for custom MTG cards, particularly for commanders, showcase cards, cube staples, and collector-style projects
If were using Solemnity as a sideboard option, it needs to be in a deck that can play removal on turn 2 and follow this on turn 3 with a threat or more removal
