You get the super fun combo only when you draw Cavalry Master and when he doesn't get destroyed/exiled.

Yes, thats why its a cheap casual deck for kitchen table games. Its the only card in magic that lives up to the pun. Sadly. Though I might add a tutor and protection for him.

Though I'm not sure if for example Agility stacks flanking like Cavalry Master, or if he's the only exception.

Yes, they stack. Rule 702.24b "If a creature has multiple instances of flanking, each triggers separately".

Consider also this combo: Hivestone + Sidewinder Sliver . They are both modern legal.

Oh that adds a nice flavour to the deck. Definately will try.

Jabari's Banner gives you another way to stack Flanking onto creatures, and Nemesis Mask is a nice way to force your opponent to block your huge pile of Flankings.

Also, and hear me out... what do you think about Infinite Reflection? It's hilarious with Sidewinder Sliver and downright insane on Cavalry Master. It's not like red is doing a ton for your deck, and using blue instead might let you have better draw power.

I thought about Jabari's Banner, but not being Modern legal, I thought not to. I wan't to play this in mtg:o. Nemesis Mask is an entirely different story, I didn't remember that card and kind of was missing this mechanic from the deck. Thanks for this man! If only I didn't have to turn this into America, Infinite Reflection would be insane! I do challenge you to build one :)

Oh actually just realized how nice it is with Knight of the Holy Nimbus.

how about Condemn/Stasis Snare/Oblivion Ring and Wrath of God?

they are possible sideboard options :)

Well Condemn is a worse Path to Exile and a playset of Paths are in and are plenty of target removal already. 1x Quarantine Field is also enough and Oblivion Ring also only gives 1 devotion and the Snare is limited to creatures. I dont really need boardclears either as one of the key mechanics of the deck provides it in the mainboard. All good SB options though, just not for this list. Thanks for your time.

If there was another way to turn your knights into slivers (without black) I would suggest Sinew Sliver, maybe even Bonescythe Sliver.

Thanks for the cool idea, widening the sliver base, though I'm not really looking to turn this in to a sliver deck. The only reason the Sidewinder Slivers are here, is their ability to stack more flanking via Hivestone, as a secondary Cavalry Master. If they print more slivers with flanking, then I'm all in for the additions (though the Sinew Sliver could work as a "Honor of the Pure" creature).

Except Sinew Sliver buffs the Automatons too. Might be worth to really test. And then I might have to up the Hivestones to 4.

You'd have to name Slivers with the Automaton though, but if you've already got Hivestone out then it would be a double boost. I'm a huge Sliver fan so converting you to the dark side will be a personal victory, lol.

Well even before this possible Sinew addition, I recommended Slivers for the Automatons in the description. Simply because of Hivestone. I've been looking around for cool slivers for couple years now, not that enthusiastically though :)

I wasn't aware that flanking stacked, that's awesome.

Cool deck too, +1

Thanks man. I didn't either, until I got my hands on some old tournament packs, including timespiral, and unwrapped a Cavalry Master. That instantly reminded me about the pimpmyride memes and forced me to build this :)

Hey sweet deck! Check out my knight tribal deck, some of the cards you've got here would actually fit in well with mine. Double Tribal Trouble

how about Coat of Arms?

Knight Exemplar looks like a better option then Adaptive Automaton

I don't think I need Coat of Arms. It would just be a win more card and doesnt help on a losing board state. As for Knight Exemplar, it already holds a spot for certain matchups in the sideboard and cant really be compared to Adaptive Automaton, as the automatons are so much more versatile. The automatons are pretty much always turned to slivers, so Sidewinder Sliver gives it Flanking and then Cavalry Master also provides the automatons several stacks of flanking.

This is both insane and amazing. Kudos to you!

Heads up: I recommended it be added to this thread over on Reddit.

Thank you, really appreciate it! I scrimmed through the reddit list and it would be nice to be a part of the unusual :)
