The goal of the deck is to get enough counters on Marwyn to go infinite or close enough that it serves the same purpose with various untap outlets, and funnel the mana into an outlet that allows the elves to overrun your opponents with either combat damage, commander damage or infect counters. This deck will often have Marwyn out by turn 2, almost always by turn 3, and the combos will assume that Marwyn is in play and available to tap for mana. The deck has several ways to achieve infinite mana, remember however that if you do not have an outlet ready for use, playing you infinity combo without an outlet ready will only open you up to being focused, as such, we want to keep the combo in hand until we need it and instead try to draw into an outlet.
Marwyn, the Nurturer + Umbral Mantle - Infinite
This combo requires Marwyn to have a power of 3 and 3 open mana. 3 pays for the Umbral mantle cast cost, 0 to equip on Marwyn, Marwyn taps for 3 mana which is used to untap her and give her +2/+2 until the end of the turn resulting in more and more mana and power for Marwyn for each untap.
Marwyn, the Nurturer + Sword of the Paruns - Infinite
This combo requires Marwyn to have a power of 2 and 7 open mana. 4 pays for the Sword of the Paruns cast cost, 3 to equip on Marwyn, Marwyn taps for 4 since she is getting the buff from being tapped generating a net gain of 1 mana with each untap.
Marwyn, the Nurturer + Staff of Domination - Infinite
This combo requires Marwyn to have a power of 5 and 3 open mana. 3 pays for the Staff of Domination, Marwyn taps for 5, 3 untaps Marwyn, 1 untaps the staff resulting in a net gain of 1 mana with each untap. This combo will win the game provided that one one stops you since it gives you infinite life, taps all enemy creatures and allows you to draw your deck which includes several win conditions.
Marwyn, the Nurturer + Temur Sabertooth + Wirewood Symbiote + any elf with cmc less than Marwyns power+4 - Infinite
This combo requires Marwyn to have 4 power more than the cmc of an elf already on the battlefield and 5 open mana. 4 Mana pays for Temur and 1 mana pays for the the Symbiote. Marwyn taps for 4 more than an elf already in play, the Symbiote untaps Marwyn by flickering the other elf in play, Marwyn's mana pays for its recast floating 4, Temur flickers the Symbiote for 2 mana and 1 mana recasts the Symbiote leaving a net gain of 1 mana and allowing the combo to unfold again.
The Symbiote can only untap once per turn with the return of an elf other than Marwyn, but we get around this restriction by flickering it back to our hand with Temur Sabertooth, as it can then use its untap ability again once played.
Interestingly this combo allows for the recasting of enter the battlefield effects in creatures, of which this deck runs basic land ramp, tutoring an elf to library top, card draw, artifact or enchantment removal and +1/+1 counter on two creatures. Additionally, many enchants and Marwyn herself proc from creatures entering the battlefield.
Marwyn, the Nurturer + Malachite Talisman
This combo is less reliable the lower Marwyn's power is and more reliable the higher it is. If Marwyn has a power of 4 she can tap for 4 mana and cast any 1 cmc green spell while leaving 3 mana open to untap herself, so the more mana Marwyn taps for, the higher cmc green spells she can cast continuously. This combo is very strong, as it is very likely that being able to cast so many green spells "for free" will result in massive card draw and drawing into a win condition.
Replacement commanders
Redundancy is important if Marwyn is being focused into the ground, therefore the deck runs the following cards as replacements for Marwyn in case she is forced from the battlefield before you can get protection for her down.
Elvish Archdruid, taps for mana for each elf you control.
Priest of Titania, taps for mana for each elf on the battlefield.
Selvala, Heart of the Wilds, by paying 1 green taps for as much mana as the greatest power among creatures you control.
Mana outlets
Once you have infinite or large amounts of mana available these outlets let you spend it to overwhelm opponents.
Ezuri, Renegade leader - Infinite
Per 5 mana he can give +3/+3 and trample until end of turn without tapping.
Joraga Warcaller - Infinite
Per 2 mana he is multikicked with he gets a +1/+1 counter and he permanently grants other elves +1/+1 for each of those counters on him. With the Temur Sabertooth or the Wirewood Symbiote he can be flickered and recast for the multikicker if you have access to some mana early on but reach infinite later.
Staff of Domination - Infinite
The staff allows for multiple uses for infinite mana and is most powerful combo with Marwyn in the entire deck. If these two cards are allowed to interact infinitely you win the game.
Genesis Wave
This allows for all permanents in the deck to be put onto the battlefield, which should be more than enoogh to win, but be careful not to draw more cards than are left in your deck or you will mill yourself out.
