Put Faeries into a graveyard if not already there by casting and/or sacrificing them.
Activate Coffin Queen targeting Faeries.
When Faeries enter the battlefield, stack the triggers to untap lands first, then untap Coffin Queen and sacrifice Faeries to Tower while Queen's exile trigger is on the stack.
Repeat from Step 2.
If a land you control (other than Tower) taps for more than one mana, make infinite mana.
