Silvanus's Invoker

Eight mana buys the oldest trick in green's book dressed up in newer clothes: untap a land you control, and it swings as an 8/8 with trample and haste while staying a land underneath. That untap clause does real work, because the land you just tapped toward the eight can be the same one you animate, folding the mana source and the threat into a single activation. The "it's still a land" line offers no protection; an animated land is a creature and dies to anything that kills creatures, and if a board wipe catches it mid-swing it hits the graveyard rather than reverting. What this really is, structurally, is a mana sink. Land-animation effects have turned stalled manabases into beatdown plans since the earliest sets, usually as one-shot spells; here the concept lives on a repeatable outlet, so every surplus land is a latent 8/8 idling on untapped mana. The vulnerability worth flagging: the Invoker is itself a creature, so any wrath that clears your board takes the outlet with it, and the sink only refills if the 3/2 survives. That 3/2 is a deliberately forgettable peg to hang the ability on, not a body you play for its stats. The Dragon Druid line is an odd flourish, two tribes that almost never share a type box, with the card behaving entirely as a druid while the dragon tag sits there as flavor. What it promises is inevitability to any deck with nothing better to do with its eighth land.
