The elegance here is that both halves of the text feed the same fantasy: turning the mana you were already going to make into a board. Most cards that animate lands hand you a body that trades on the ground into whatever is bigger; this one gives every animated land evasion, so a 3/3 land only has to answer to fliers and reach. The seven-land gate is the pressure valve, asking you to have gotten well into the game before the engine matters, which is why it lives naturally alongside ramp and landfall shells that were already flooding the board. Note the second ability triggers on any land entering, not just the ones you play from hand, so anything that recurs, blinks, or drops extra lands per turn multiplies the tempo. The animation is one-shot per land per trigger and targets up to one land, so it accrues rather than converting the whole board at once. Crucially, the change is permanent: an animated land is a creature until it leaves or dies, which means it counts as a real threat but also exposes your mana base to every sweeper and creature-targeting kill spell on the table. This is a payoff build-around that rewards the specific overlap of ramp, evasion, and recursion in a way the standalone rate never advertises.
