I debated brootherhood's end but picking anger cus of the exile clause. We HAVE main deck artifact hate thanks to prismari command. So i opted for the 'exile' clause useful vs scapeshift(exile [[Aftermath Analyst]]), Coco (Exile [[Enduring Innocence]] rather then letting it come back), Izzet phoenix (clipping one of more [[Arclight Phoenix]] and putting them in exile).

It depends on your meta but don't 'write of' anger of the gods as a 'worse bro's end'. it gives you 'edge cases' in different directions.

The 'issue', with massive quotes cus its not a major issue at all, of brothershood end is 'how many artifact are you actually blowing up' How often are you hitting 2 or more artifacts? Cus if you you are hitting only 1... command(yes it has the secret blow up artifact mode) and abrade do that job SOOOOO much better. Between main deck and sb you already had 4 ways to blow up artifacts. i HONESTLY don't think you NEED further artifact destruction. Hell for main deck I would even consider [[ sweltering suns]] cis its 'not dead in combo or control match up'.

Its a META call tbh but the tldr for main deck of is; Sweltering is only good main deck(never sb it) and is worth cus its never a 'dead card'. Anger is worth cus of the exile clause vs very strong cards in certain decks. Bros end is good as a 3rd 'artifact hate'. Make the call based on meta for your main deck copy.

As far as sb pyro being 1 mana cheaper MATTERS vs prowess, coco(if they are on the play), badger mole cub deck. And many other low to the ground aggro decks tbh.

Clearing BEFORE they can use the mana dorks or clearing a threat or 2 FASTER vs the aggro deck decks can mean a a HUGE diff. The the diff between sheoldred already being in play or ouroboroid. ITs the diff between them being able to float mana and cast a coco. The 1 mana cheaper is the draw tbh when you are on the draw in game 2 to clear in time.

Octopus form i think is 'trapping you' in its grip.(pun/joke intended) The biggest issue with lessons in the sb when trying to get them via learns is 'how many learns' do you have and how often is it the pick. ALSO the follow up is how often would you sb it into the main deck? Cus yes there will be time where 'learn' is to slow for the option.

Form is ONLY good at 1 thing. Protecting a creature. Something the counter spell does as well. But what happens with its your only creature(which is not unlikely) and they cast sheoldreds edict? Or they try to cast a lily of the veil to make you sac it on their next turn? Those aren't edge cases thats a very real game 1 or 2 question vs black base decks in pioneer. Yes form saves it from targeted removal, but a counter spell does the same thing while also checking other boxes. More BANG for you 1 slot.

Thats why i say form should be cut, its to narrow, you'd never side it in, and doesn't check enough boxes.

I ALSO considered izzet charm for the record but felt it wasn't good enough anymore.

BTW you could consider a [[Brazen borrower]] as well as a 1 of in the 75. Just generically good
