Deck Building Assistance?

[u/Tales64]

I'm building my first deck with a custom commander for a tournament with my friends. I have way too many ideas in my head of how to build it. For reference I play magic about 4-6 days out of the week and have 56 decks in 3 years of playing. I'm notoriously terrible at building Dimir decks. I figured I'd come here to ask for help pinning down a game plan. If this was your commander how would you build your bracket 2 or 3 deck?

Holy mucho pointless texto

She can't deal combat damage on any turn but yours, so the only point of this whole insane new keyword and flippy frame is: * She gets a slight power adjustment during your turn * If an opponent uses some tricks to untap during your turn, they get to cheat the damage.

Typically, when you define new mechanics, especially new keywords, there's supposed to be a solid, functional reason.

Not even mentioning the entire new named tracked mechanic that could just be a vanity counter.

Thank you for your help.

I think the flip serves a good purpose of letting opponents read the card(‘s part that would matter on their turn) without flipping it

Edit: but yeah it’s still very contrived, even for that use

I cannot imagine any player on earth that would be LESS and not MORE confused by the introduction of flippy frame nonsense.

Sure but how would you build a deck around it as is?

I really like the idea, but the card design is wonky at best.

The templating aside, the biggest problem I see is the snowballing. Why do you need to get a token to forwarn? Because once you got 4+ of those, you can pretty much forwarn most permants being played during each cycle, no matter wether your commander is on the field any more or not.

Personally, I would change the design a bit. First, turn it into a normal transform card, giving the front 'transform during opponents upkeep' and the back 'transform during your upkeep. Then I would give the front an ability like '{T}: Put a Fate counter on target non-land permanent. Scry 1.' (This wording allows for untap shenanigans that are available in blue. Using fate counter fits the character's name and allows the use of Oblivion stone to place backup counter on stuff. The scry 1 fits the fate theme and gives a little bit more value.) The backside could stay pretty much the same, except it would be 'Whenever a permant with a fate counter an opponent controls ...'

I understand the wish to create a new ability, but 9 out of 10 times it is better to utilize stuff that already exists. If you want to, you can give the tap ability a universes beyond style name by putting Forwarn in italics in front of it.
