The Peregrine Dynamo (Extended Art) [Dominaria United Commander] Phyrexian Knight While the gremlin

While the gremlin

When Floriferous Vinewall enters the battlefield

the caves once again echo with the grisly sounds of Phyrexians preparing for war

When Faerie Seer enters the battlefield

for each RR spent to cast it
