(Infinite) COMBOS:
Devoted Druid + Vizier of Remedies + (Walking Ballista, Ezuri, Renegade Leader, Leyline of Abundance)
Start with Devoted Druid and Vizier of Remedies on your board. Tap and Untap Devoted Druid as many times as needed to cast an arbitrarily large Walking Ballista (or put infinite +1/+1 counters on it if you have it in play), or activate your Leyline of Abundance infinite times and put infinite +1/+1 counters on your creatures, or maybe use Ezuri, Renegade Leader's Overrun (The one for two green and three colorless) ability to make your Devoted Druid, Himself, and other 1-Drop elves (such as Llanowar Elves, Elvish Mystic, and Boreal Druid) arbitrarily large.
Devoted Druid + Leyline of Abundance + Ezuri, Renegade Leader
This combo is a bit harder to figure out. With your Leyline of Abundance, Devoted Druid, and Ezuri, Renegade Leader in play, first tap the Devoted Druid for two green (instead of one due to Leyline of Abundance). Next, Untap the Devoted Druid by putting a -1/-1 counter on it. Tap it for another two green. You now have four green mana in your mana pool. Find some way to generate one more mana, perhaps through an untapped land or spare 1-drop elf (such as Llanowar Elves, Elvish Mystic, and Boreal Druid). Next, spend that mana on Ezuri, Renegade Leader's second ability, giving your Devoted Druid and itself +3/+3 until end of turn. Now that your Devoted Druid is a 3/4 until end of turn, you can use it's untap ability again! Untap and tap the Druid three more times. You now should have 6 green mana (due to Leyline of Abundance, and a 0/1 Druid. You can use this mana to activate Ezuri, Renegade Leader again, and make your Druid a 3/4! If you keep going from there, you end up with infinite mana! You can spend this on any of the aforementioned mana sinks (also note that at this point Ezuri, Renegade Leader and any other elves on your side of the table are arbitrarily large), and win from there.
Yawgmoth, Thran Physician + Kitchen Finks + Vizier of Remedies
With the current list, this combo doesn't really let you win, but can do some interesting things. First, have all three cards on your board. Then, sacrifice your Kitchen Finks to card: Yawgmoth, Thran Phyiscian, causing the Finks to persist, and gain you 2 life. You now have one more life than you you started with, a creature your opponent controls has a -1/-1 counter on it, and you drew a card. Your Kitchen Finks don't have a -1/-1 counter due to Vizier of Remedies, so you can do it again. Draw as many cards as needed. You probably have means to win in a turn or two, and comment any suggestions for cards that let you win with your deck in your hand w/o infinite mana (and preferably is on color). Think ways to give a Devoted Druid haste on that same turn.
Note that there are other combos in this deck, I am just lazy and will put them in this description soon.
