This loop is driven by the clever synergy between Ant Queen's token-creation ability and Jaheira, Friend of the Forest, which turns every token into a mana dork capable of tapping for green mana. Normally, paying {1}{G} to make a single Ant Queen token wouldn't generate a profit, but Elspeth, Storm Slayer steps in to double every token creation, instantly yielding two Insects instead of one. Since those two new tokens can each tap for {G} through Jaheira's static ability, you get back the exact green mana you spent while netting an extra green mana and a surplus Insect each iteration. Meanwhile, Kratos, God of War hangs back on the battlefield granting your growing army haste, ensuring that the endless wave of newly entering creatures can immediately join the fray without waiting.
