Tiamat Dragons - Food Chain v2 (EDH / Commander)

Simple and effective Tiamat deck. Plays a few combos; however no Bladewing combos (Bladewing the Risen + Moritte of the Frost etc.) or infinite mana combos (Squee, the Immortal / Eternal Scourge with Food Chain).

Combos:

1. Aggravated Assault:
   Aggravated Assault + Ancient Copper Dragon/Old Gnawbone/Savage Ventmaw/Scion of the Ur-Dragon (copying one of those dragons)/Tiamat + Faeburrow Elder or Bloom Tender. Infinite combat phases.

2. Dragon Tempest:
   Dragon Tempest + Ancient Gold Dragon / Scion of the Ur-Dragon (copying AGD), triggers Dragon Tempest’s heavy damage stacking. If you have Aura Shards in play it adds a nice bonus of destroying as many enchantments and artifacts as you can.

3. Food Chain:
   1 turn kill. Pre-reqs: Food Chain is in play, and there is enough mana to cast Tiamat. If you don't have enough mana but have one or more creatures in play like Birds of Paradise, Faeburrow Elder, Bloom Tender, Dockside Extortionist, Rivaz etc. you can exile them with Food Chain to cast Tiamat earlier.
   a. [Here's an example of a Dragon combination I like]: Cast Tiamat searching up Hellkite Courser, Miirym, Sentinel Wyrm, Atarka World Render/Dragonlord Dromoka/Dragonlord Kolaghan, Ancient Silver Dragon, Old Gnawbone.
   b. Use Food Chain to exile Tiamat for red to cast Hellkite Courser (#1), getting her back on the battlefield with some red mana remaining.
   c. Exile Hellkite Courser to Food Chain for green, plus Tiamat for blue (2r,7g,8b)
   d. Play Miirym, Sentinel Wyrm (#2), 11 mana remaining.
   e. Play Atarka, World Render (#3), create a copy. Exile the copy. 12 mana remaining. (If no haste card is in play, play Dragonlord Kolaghan instead; will need 1 extra mana for black. If you're worried about removal you can search and play Dromoka instead but need 1 white. If you have no extra black/white mana sources but have one of the 1-3 CC creatures in play you can exile one of those.)
   f. Play Ancient Silver Dragon (#4), create a copy. Exile the copy. 13 mana remaining.
   g. Play Old Gnawbone (#5), create a copy. 6 mana remaining.
   Hit for huge damage, create treasure tokens, and draw lots of cards. Play Tiamat again, lots more cool dragons to search for. At that point you can pretty much wipe the board by casting either Aggravated Assault or Terror of the Peaks and the rest of your dragons.

Without Food Chain or other combo cards in hand, the deck still has lots of ramp and can get out Tiamat quite fast.

Notes:
-If you want flexibility to cast creatures with more mana types tutored by Tiamat (with Food Chain in play), Prossh, Skyraider of Kher is a good option.
-For a more competitive version of this deck:
Squee, the Immortal or Eternal Scourge with Food Chain gives an infinite mana combo.
Jeweled Lotus is great at speeding up the casting of Tiamat.
Dream Halls also works well with the deck; for the Dream Halls + Tiamat combo (search it on google) you'll need to add Moritte of the Frost & Bladewing the Risen to the deck.
Revel in Riches can be a finisher with the many avenues for generating treasure tokens.
