God/Tree Legend Tribal (YT decktech) (EDH / Commander)

Here's how the combo works:

Version 1 - you need [[Esika, God of the Tree]], [[Najeela, the Blade-Blossom]] and 3 legendary creatures on the board.
Go to the declare attackers step.

1. Attack with all 5 creatures (they all have vigilance).
   (1.5 Najeela's first ability will triger. Let it resolve or don't, it's not part of the combo)
2. Tap all 5 creatures for WUBRG mana combined.
3. Activate Najeela's second ability paying WUBRG.
4. Let it resolve. Your creatures are now untapped an you get an additional combat phase + some goodies. Return to step 2.

When you add any additional creature you have infinite mana, that you can e.g. sink into [[Sisay, Weatherlight Captain]] or [[Kenrith, the Returned King]].
When you add any creature with a tap ability you can use it an infinite number of times, e.g. [[Captain Sisay]].

Version 2 with [[Esika, God of the Tree]], [[Najeela, the Blade-Blossom]] and [[Kinnan, Bonder Prodigy]] + 2 Lands (or sth similar) that can produce mana of different colors.
Go to the declare attackers step.

1. Attack with all 3 creatures (they all have vigilance)
   (1.5 Najeela's first ability will triger. Let it resolve or don't, it's not part of the combo)
2. Tap the lands to produce 2 mana, e.g. white and green.
3. Tap the creatures to produce UUBBRR mana due to Kinnan.
4. Activate Najeela's second ability paying WUBRG. There is UBR left in the pool.
5. Let it resolve. Your creatures are now untapped an you get an additional combat phase + some goodies. Return to step 3 but now tap for WWGG + any color.

This can again be looped to get infinite mana, untap and combat phases, you just have to make sure you always hit your missing colors in this loop. It is shortcut-able so no worries.
