Mana Untapper

Effects that untap lands or other mana producers within a single turn, letting the same sources tap for mana more than once. Includes ETB untappers like Palinchron, Peregrine Drake, Great Whale, and Cloud of Faeries; spells like Frantic Search and Turnabout; and repeatable enablers like Candelabra of Tawnos and Dramatic Reversal. When paired with a producer that taps for more than its untap cost, these often go infinite. Narrower view of mana_combo.infinite_mana_piece, which more broadly covers full two-card loop enablers; this id specifically isolates the untap-mana-source mechanism rather than mana_combo.mana_doubler multiplication or mana_combo.mana_sink payoff outlets.
