Marwyn, the nurturer - Glass Cannon combo (EDH / Commander) [Revision 15]

make infinite mana and large elves with Marwyn, the nurturer!

main combo.
marwyn, the nurturer + umbral mantle. play the manlte for 3 mana and equip it to marwyn. if marwyn makes 3 mana, tap her for 3 mana and activate the ability of the mantle. marwyn will be untapped and now she wil produce 5 mana from the +2/+2 ability from umbral mantle. repeat the loop for infinite mana and one big marwyn.
sword of the paruns does somewhat the same but marwyn won't be big. she will get the extra 2 power form the sword because mana isn't add before she is tapped.
ps. if you have infinite mana with the mantle on the field don't forget to equip to your other elves to make them big aswell.

viridian joiner does the same as marwyn. so if marwyn has been removed to much you can count on viridian joiner to do the job aswell.

wirewood channeler, elvish archdruid, priest of titania are not like veridian joiner or marwyn but if they're big enough, they will do same with mantle or the sword.

Other combo's

leyline of abundance + ezuri, renegade leader + devoted druid: so if everything is on the battlefield, ready to use, and 1 mana available, you can now tap devoted druid for 2 times 2 mana. wich gives you enough to activate ezuri's ability to give every elf +3/+3 until end of turn. your devoted druid is a -1/1 before the activation and afterwards a 2/4, so now you can tap her 3 times to add 6 mana to you mana pool. repeat the loop for big elves and infinite mana.

marwyn the nurturer + temur sabertooth + wirewood symbiote + a one-mana dork: this is rather long but not so uncommon. Tap marwyn for atleast 2 mana, use the symbiote to untap marwyn and return the one-mana dork. play the one-mana dork so marwun grows bigger. marwyn is now untapped but taps for 3 mana. tap her to have 4 mana in you mana pool. return the symbiote to your hand using the termur sabertooth. you have now 2 mana left. play the symbiote for 1 mana. you have 1 one mana left. untap marwyn with the symbiote (is says once each turn but if you re cast it, it enters as a new creature wich resets the ability) play the dork with the single mana left in the pool. marwyn taps now for 4 mana. repeat for infinite mana and ETB's.

the rest is self explemantory.

it's NOT the most perfect build for marwyn and that's because of the elf tribal element in here. a GOOD marwyn deck is build with other cards to make marwyn way bigger and more early. but we all love a good tribal deck and this is a good one !
try to start with at least 2 lands and a mana dork. one land hands can be done but it's tricky and dangerous!
watch out for boardwipes because it can be challenging to recover from it.
