Mana Doubler

Permanents that multiply mana output rather than producing a fixed amount, turning every tap into double or triple the yield. Mana Reflection and Nyxbloom Ancient scale all mana sources, Zendikar Resurgent adds an extra mana whenever a land taps, and Vorinclex, Voice of Hunger and Mirari's Wake trigger off land taps for bonus mana. Distinct from mana_combo.infinite_mana_piece, which enables two-card loops for arbitrary mana, and from mana_combo.mana_untapper, which reuses sources by untapping them rather than amplifying each tap.
