Codie, Vociferous Codex + Necrotic Ooze + Leech Bonder

Codie, Vociferous Codex

Necrotic Ooze

Leech Bonder

How it works

1. Activate Necrotic Ooze using Codie's ability by paying 4 and tapping it, adding .
2. Activate Necrotic Ooze using Leech Bonder's ability by paying and untapping it.
3. Repeat as desired, skipping step 2 on the final iteration.
4. Cast any spell by paying its mana cost, reduced by the added in step 1.
5. Necrotic Ooze triggers for each time you activated Codie's ability.
6. Resolve the first trigger, causing you to exile cards from the top of your library until you exile an instant or sorcery spell with lesser mana value, and allowing you to cast that spell without paying its mana cost.
7. Repeat step 6 for each remaining trigger.
8. You may also repeat this combo for each nonland card in your hand as mana permits, and on subsequent turns.

This ingenious loop turns **Necrotic Ooze** into a dual-threat engine by leveraging creatures resting in the graveyard. By absorbing the activated ability of **Codie, Vociferous Codex**, the Ooze can tap to generate a massive burst of five-color mana while triggering a cascade-like plunge into your library. Meanwhile, grafting on **Leech Bonder**'s untap-and-counter-moving ability allows you to repeatedly untap your Ooze, fueling endless activations of Codie's ability as long as you can pay the blue mana required.
