Plus it's very fair, since you aren't taking anything they weren't intending to use against you
However, if a Lion Umbra you control is attached to a creature you don't control and that creature has no Auras controlled by that creature's controller attached to it, no Equipment attached to it, and no counters on it, Lion Umbra will be put into its owner's graveyard due to being attached to an illegal object the next time state-based actions are performed
Ive also been enjoying a sub-infinite variation with my Hylda deck in budget Commander
So the question becomes: does a Sacrifice deck want Village Rites if they're already running Skullclamp
He earns that six-mana casting cost though, since he lets you make non-legendary copies of each historic spell you cast
This is probably worth at least -3 mana on its own, but it at least comes with one benefit: it skips a roomand that might just be worth +1 mana if your deck really wants to complete a dungeon ASAP
