Sweet deck! I'm definitely going to to try an Azlask 5 Colour Experience Tribal

Here are a few cards I'm running in mine: Echoes of Eternity (2-3 euros) - 3 colorless mana, 3 mana of any type. Enchantment. This will double the triggers of any colorless spells you have in play and it will copy any colorless spells that you cast, that includes spells with the Devoid tag and artifacts you play. I think this is probably the best card in the deck. Angelic Aberration (pennies) - 1 white, 5 mana of any type. 4/4 eldrazi angel creature with Flying and Vigilance. Devoid. ETB: Sacrifice any number of creatures with base toughness 1 or less (scions, spawns and plant tokens), make them into 4/4 Eldrazi Angel tokens with Flying and Vigilance. This is another win condition in itself. (This card is in the precon if you already have that) Morophon, the Boundless (5-8 euros) - 7 mana of any type. 6/6 shapeshifter creature. You choose a creature type, Eldrazi. All your eldrazi creatures get +1/1 (including Morophon). Eldrazi spells will also cost 1 less white/blue/black/red/green mana to cast, this only applies to colored mana you pay. If Morophon is on the field, you can play Ulalek for free as he costs 1 of each colored mana. Also a lot of our creatures cost 1-2 colored mana, so this helps to mitigate that. (This card is in the precon if you already have that) Herald of Kozilek (pennies) - 1 blue, 1 red, 1 mana of any type. 2/4 eldrazi drone creature. Devoid. Colorless spells you cast cost 1 colorless mana less to cast. Urza's Incubator (5 euros) - 3 mana of any type, artifact, reduce the cost of all Eldrazi creture spells by 2 colorless mana. Maskwood Nexus (2-3 euros) - 4 mana of any type, makes all your creatures have the Scion/Spawn tag for Azlask's ability which now gives all your creatures indestructible and annihilator 1. You can tap it and pay 3 mana of any type to create a 2/2 shapeshifter token, which is also an Eldrazi, Scion and Spawn due to the shapeshifter tag. Eldrazi Confluence (2-3 euros) - 2 colorless mana, 2 mana of any type. Instant. It's a choose three, and you can pick the same option more than once. 1) Target creature gives +3/-3 until end of turn. 2) Exile target nonland permanent, then return it to the battlefield tapped under it's owner's control. 3) Create a 1/1 colorless Eldrazi Scion. It's a removal spell, it can blink your own creatures to trigger their ETB ability or it can simply make you 3 scion tokens. It outclasses "Call the Scions" by a long shot. (This card is in the precon if you already have that) Victimize (pennies) - 1 black mana, 2 mana of any type. Sorcery. Choose 2 creatures in your graveyard, sacrifice 1 creature, if you do, bring the 2 creatures back to the battlefield tapped. Sac a spawn, bring back Drowner of Hope + Angelic Aberration as an example. You create 3-5 4/4 eldrazi angels + a 5/5 eldrazi. Or bring 2 of your ETB token creators to get 4-8 eldrazi spawns/scions. Urza's Cave (2-3 euros) + Urza's Powerplant, Mine and Tower (2-3 euros in total). Lands. Urza's cave taps for 1 colorless, or you can tap it and pay 3 mana of any type to search your library for any land card and put it into play tapped. We're already running Sowing Mycospawn + Sylvan Scrying which can search out non basic land cards too. So it should be relatively easy to get all 3 Urza's lands into play, which tap for 7 colorless mana in total when all 3 are on the battlefield.

An alternative to elven chorus i think that works better is mystic forge. It lets you cast colorless and artifacta spells off the top, so unlike elven, top decking one of your rocks doesnt stop you and forge lets you pay 1 life once per turn to exile the top to maybe get around a land. Its also 4 generic, so no colored mana to wory about like chorus thought thats a minor issue

Ashnods Alter goes infinite for scions/spawns and infinite colorless mana (which can be any color mana if you put Chromatic Orrey in the deck) with Eldrazi Displacer flickering "Brood Moniter or "Emerakles Hatcher", either creates 3, and you sack 2 to Ashnods for 4 mana using 3 to flicker with displacer... infinity mana, infinite counters and infinitely big after the commanders activation. Then with any number of ways in 5 colors to give them all haste.

Small correction. Flayer drone pings one target opponent. Awesome video though! Forgot about catacomb sifter and for sure slotting that in.

When token copies are exiled (chittering dispatcher or mirror march), Azlask won't trigger, right? From what I understand, them getting exiled doesn't count as "dying", and dying only happens if they get destroyed by spells or damage, or sacrificed.

As soon as i saw Azlask i wanted to build him. Dident think about adding other exp gain cards in. And yours is more budget friendly.

This deck is $281 pre tax 🥲
