I'm trying to make a commander deck with Niv-Mizzet Reborn and it is proving to be challenging.

Niv lets you look at the top 10 library cards and pick one card per two color pair, so I'm trying to have roughly equal cards for each pair. The main strategy is to search/mill out General Ferrous Rokiric and then make a bunch of 4/4 guys to attack with while being controlly with instants and sorceries. Other features are:

1. 2 color blink spells, either repeatable or instant speed. Such as Abuelo, Ancestral Echo and Soulherder. Repeats the niv tutor ETB
2. Lord of the Nazgul and Judith, Carnage Connoisseur for more token production.
3. Tutors for Rokiric such as Ringsight and Perplex (3 mana transmute)
4. MDFC dual lands that can be tutored by Niv
5. Spell-slinger accellerators like Rashmi, Eternities Crafter and Prosper, Tome-Bound and Lilah, Undefeated Slickshot
6. Other payoffs like Kalamax and Arixmethes, Slumbering Isle (12/12 that is ramp until you play 5 spells)

Questions I have are:

1. Do I need more unconditional draw to draw lands, mana rocks, and other mono-color cards?
2. Should I also include cheaper payoffs like Witherbloom Apprentice (I gain 1 life and opponents lose one life per instant/sorcery I cast)?
3. Is having unlimited hand size a priority, and if so, will it make me the arch enemy?
4. Is this deck too slow? Typically it's producing creature tokens by turn 5 to 7.
5. Rokiric has hexproof from mono-colored. Is that enough to protect him alongside having blinks available? I have some creature yard recursion in case of forced tributes.

Pauper is my favorite, so much room to brew and such a wide open metagame. Even though there's a huge card pool, new sets still often shift the meta enough to keep things fresh, without totally nuking the format like Modern.

It's a powerful format but without a lot of individually powerful cards, so you see a lot of unusual and kind of janky synergies you don't really see anywhere else.

A competitive deck costs as much as one shockland so you can put something together on a whim and experiment.

I mostly play dimir terror, but also have pestilence, elves, and orzhov blade decks I'm kind of iterating on.

Pioneer is also pretty good. And I play commander, like everyone, but I've been less interested in it lately.

1: I play a lot of Pioneer (because it encapsulates basically every set I played) and Commander because it's what everybody plays. However, I've recently been enjoying Pauper more. The People's Format.

2: Arcades, The Strategist + A Fuckload of Defenders + Tower Defense

Alternately, any Lotus Field Combo.

About to do a Winston draft this weekend with my BiL. 3pk Crimson Vow, 3pk Karlov Manner, which feels like a reasonable thematic match (and it's what I've got laying around). Plus a few promo packs thrown in for extra spice.

Very excited! Haven't been able to go draft for real for a few months since my latest child was born.

Hoping to pull a Sorin for the wifey while we're at it.

check out this custom card I made

TQ1: My favourite format is cube . A guy at my LGS has an (outdated) vintage cube that we've been playing sometimes, and I've begun work on my own. Planning to include silly un-cards and playtest cards for shits and giggles. Anyone here have experience designing a cube?

also commander I guess

when we dont play cube I'll play commander and then usually a Gruul big stompy deck .

TQ2: My favourite combo is Hoarding Broodlord -> Fetch Saw in Half, Cast it on the Broodlord, tutor 2 more cards up, go wild!

I don't play much anymore. I used to love magic, but lately, the constant barrage of new product is too much for me.

But I still do play commander with my friends. Not too often but whenever we get together a game or two is inevitable.

My favorite deck is Tatyova, Benthic Druid, and my favorite non infinite, not guaranteed to win combo is (with Tatyova on the board):

Avenger of Zendikar into Scapeshift.

I get an army of huge plants, gain a bunch of life and draw a shitload of cards.
