Celestial Wizardry ~ Magical Astronomy (Inalla EDH) (EDH / Commander)

Outvalue your adversaries with the most powerful magicks of the realm. Reset the board every other turn and assemble a combo win, or outgrind your opponents with infinite value.
As a combo-based deck, it may not be for everyone or every playgroup. You can easily remove the most combo-y cards (Ashnod's Altar, Wanderwine Prophets, Timestream Navigator, Mistbind Clique) and still have a pretty good control deck. If you do, add a couple more of wincons.

A couple of considerations:

• Inalla, Archmage Ritualist hardly if ever needs to leave the command zone. You only need her eminence ability. This makes her invulnerable to removal. She enables all of the combos in this deck.
• Ashnod's Altar is the prime combopiece of this deck. It goes infinite with Bloodline Necromancer, as you can sac him in order to revive himself with his copy (which you pay with Altar's mana). This nets you infinite mana and Necromancer tokens, from which winning the game should be easy. The altar also permits you to pay for the Mistbind/Wanderwine loop.
• Wanderwine Prophets is a 1-card combo. The way it works: you put Inalla's trigger above the champion. You use the token to champion the Prophets (and thus you don't need to champion the original). When you deal combat damage with the token, sac it to itself. This should return the original to the battlefield, and you repeat the process (champion w/ the token). You only need someone to hit every turn and you can take all of the turns.
• Mistbind Clique with Altar or any sac outlet, you can use the champion trick in every oponent's upkeep to tap them out.
• Timestream Navigator combos with anything that can return her to your hand (Crystal Shard). Cloning the token and activating its ability should net you infinite turns.
• Sundial of the Infinite lets you keep your tokens forever. Inalla's ability is a delayed trigger that removes the tokens at end of turn. In response to the triggers, you can activate sundial. The triggers are exiled (and wont trigger again) and thus the tokens stay.
• Venser, Shaper Savant can return itself to your hand and function as a pseudo Capsize.
• Clone Legion goes infinite with anything that clones or returns spells.
• You can bounce Master of Waves and keep its tokens if you have a clone. This is relevant when you have a lot of mana or Sundial.
• You are fairly resilient to wraths. Don't be afraid to wrath your own dudes.
