Random Rainbow Bullshit Go! (EDH / Commander) [Revision 12]

This deck aims to chain tutors (i.e. tutor for conflux to tutor for tiamat to tutor for combos) in order to vomit random rainbow bullshit onto the table and win in 1 turn Basic combo is as follows:
Jodah, Archmage Eternal (or Fist of Suns): Cards can be cast for WUBRG
Jegantha: Taps for WUBRG
Chakram Retriever: Untaps Jegantha when a spell is cast
Moonveil Regent: Casting a spell lets you discard your hand and draw for each of it's colors.

Play all of your cards. Eventually play Leyline of the Guildpact + Iridian Maelstrom to wipe everyone else's board. Scion of Draco gives Jegantha vigilance because you have Leyline of the guildpact. Attack with Jegantha, then tap to use Najeela's ability and untap Jegantha. Repeat 2147483647 times for many combat steps. Kill everyone.

Jegantha instead of Jodah in the command zone because it appears less threatening and plays into the backup plan of just playing big spells. Also we have redundancy for Jodah, but not for Jegantha.

Leyline of the Guildpact + Iridian Maelstrom = In Garruk's Wake
Leyline of the Guildpact + Scion of Draco = Shitty Akroma's Memorial

Conflux Targets:
Leyline of the Guildpact - almost always grab Leyline because lots of the cards in this deck are more powerful with it.
Chakram Retriever/Jeskai Ascendancy - use with Jegantha and Jodah/Fist of Suns to play all the cards from your hand.
Tiamat - Tutor 5 more cards. Insanely good in this deck. Consider Congregation at Dawn instead if you already have Tiamat.
Jodah, Archmage Eternal - use with Jegantha and Chakram Retriever/Jeskai Ascendancy to play all the cards from your hand.
Heroic Intervention/Teferi's Protection//Veil of Summer - Protect your board for the turn where you combo. Consider Firemind's Foresight for all three.

Tiamat Targets:
Scion of Draco - Very good with Leyline of the Guildpact.
Kyodai, Soul of Kamigawa - Another instant speed protection piece, like Heroic Intervention or Teferi's Protection.
Moonveil Regent - Once you have the infinite assembled, this lets you go even further beyond. Eventually play Najeela, the Blade-Blossom for the win.
Two-Headed Hellkite, O-Kagachi, Vengeful Kami, Niv-Mizzet, Guildpact, Niv-Mizzet Reborn - For use with Moonveil Regent.

Congregation at Dawn targets:
Tiamat, Jodah, Archmage Eternal, Chakram Retriever
