Zendikar Resurgent

Two of green's favorite payoffs welded onto one enchantment: the mana doubler and the creature-cast cantrip engine. The doubling is the more demanding half, because it triggers on tapping a land rather than producing mana globally. It reads the type of mana each land made and matches it, so a tapped Forest yields two green, a dual yields two of whatever you chose, but mana from rituals, rocks, and creatures stays single. That distinction shapes how the card rewards you: the more your ramp lives on the battlefield as lands, the more the doubler pays. The second clause turns every creature spell you cast into a fresh card, and crucially it triggers on the cast, not the resolution, so you draw even when the creature gets countered or fizzles on the way down. That cast-trigger timing is where the engine earns its keep. Most ramp asks what you do once the mana arrives and leaves you to find the answer yourself; this one keeps refilling the hand each time you commit a creature spell, so a creature-dense deck never empties out. The cost is the obvious friction. Seven mana for an enchantment with no immediate board impact invites a removal answer before either trigger fires. It belongs to the lineage of top-end green engines that pay you back only on subsequent turns: you are not buying tempo, you are buying a slope, where every land tap and every creature thereafter compounds. The reward is real; the question is whether the table lets you have the turn after.
