Alright -Arcanity-, here's the deal: Unmoored Ego is in the sideboard to deal with A)big annoying combos that I don't want to have to deal with or B)shenanigans that can't be countered and/or can't be nuked, see Carnage Tyrant. It is there to deal with things that can cause me problems, however, since not all decks cause me problems and I'm able to run them over before they're really going it's not in the mainboard. It is there as a roadblock to whatever their primary plan is and force them to shift plans, while mine goes on, relatively undisrupted because by the time I have to cast Unmoored Ego, I'm already rolling and I'm keeping them from disrupting my game plan. Alternatively, as I've said both here in the comments and in the description, I can tear lands out of a mana-intensive deck, which gives me an advantage.

This deck is by no means meant as a Tier 1 Standard deck, I have neither the money nor the patience for that. It is meant as a fun deck that abuses a mechanic to the nth degree and still wins games. You're entitled to your opinion about it, but at the end of the day it's just your opinion. But what do I know, I've only been in since Odyssey.

Archiving prior comments.

Btw GingerSquatch93 I wasn't asking you for how long you've been playing. I was asking DragonKing90.

I'd consider moving Sinister Sabotage to the sideboard in favor of Thief of Sanity. This seems like a deck that wants to be actively playing things on turn 3.

Also, get you a Field of Ruin or two. Azcanta is a problem, and with Selesnya being a real threat, you'll want to have something for Adanto as well.
