Hello happy folks I hope you are having a most bounteously awesome day today! Today I wanted to look at my Top Support Cards for the X-Matters Archetype in Commander! Last week I looked at Commanders here: (https://www.coolstuffinc.com/a/abesargent-seo-02102025-the-top-commanders-for-x-spells). This is not X Spells themselves but the support infrastructure to make them work...ready?

Honorable Mention

Elminster

This five mana Azorius planeswalkers is first with five loyalty and a static to drop your cost of instant and sorceries this turn by how much you scried. You can then +2 him to draw and scry two for two cheaper spells and card draw and run scry card draw cantrips like Serum Visions and Opt here and then you can -3 him to exile the top card of your library to make 1/1 Blue Faerie Dragon dorks equal to its cost. Great with scry set up. Here you want to drop your X cost massively with that scrying and then get a much bigger spell that turn, ideally from permanents like Crystal Ball or this. Note he can be your Commander too in case you wanted to dig that way, but I like I him here as a support piece.

Selvala, Heart of the Wilds

This three-drop 2/3 legendary green colored lady is next who is card draw for the biggest power on arrival to the battlefield of each dork and your foes will draw too. Then you can tap her with a green mana to make mana equal to your highest power, and with an X spell Hydra like an 7/7 you have already you now convert one to 7, and drop an 13 with that mana for the next one, draw and then have 13 even more and can win fast with their size or make enough mana to win with stuff like Staff of Possession, Fireball and other stuff.

Herald of Secret Streams AND Winged Hive Tyrant

Our final before the Top 5 proper is this duo that gives evasion for dorks with counters on them. The blue Merfolk gives them the best evasion with unblockable but just for +1/+1 counters great for Hydras and stuff though. The five-drop Izzet one with flying and haste gives them all the same, both better with haste so they can swing now and worse with flying vs unblockable pure.

#5. Nyxbloom Ancient

This mono-green triple green mana seven-drop 5/5 trample enchantment creature is next! It triples your mana production from lands to rocks like Sol Rings to dorks like Birds of Paradise. Without work it's here to triple that X spell you are casting each turn. It's downright nasty with Selvala above!

#4. Doubling Season et al

Next are permanents that double your stuff on arrival. If you are just running Hydras and X spell dorks that arrive with +1/+1 counters, then things like Branching Evolution and Corpsejack Menace work fine. But if you've got some X spells in there with X mana dorks like Decree of Justice then Doubling Season is best. Love it much, you will too!!

#3. Nexos

This two mana Bear size green rare is next! Your basics will tap for two mana for just X spells and costs though. Note costs like Lair of the Hydra work too. Love this cheap mana enabler early! Enjoy much!

#2. Elementalist's Palette

This three mana tapper of any color like a Manalith is next! When you cast those spells of an X nature toss a pair of charge counters here! Then you can tap it for colorless to make that many mana of colorless and then it can only be used for X spell costs. Love it much since the latter ability doesn't remove the counters! Many misread that. Love it much to cast your spells!

#1. Unbound Flourishing

This three-drop enchantment mythic tops our list! It turns a cast of a permanent or with X cost in it to double the result or if a spell copy it! Nasty stuff there all up and down the block and left and right too! Love its power in any X spell deck from Hydras to Comet Storm! This breaks this in half.

There we are, what are your thoughts??? I have a real-life X Spell matters around Rosheen. What's yours and do you agree with this list in this order? Let me know your thoughts!
