So as far as we know, each clan is only going to have access to one particular Imaginary Gift . Some are confirmed, as I have listed below, but the ones next to "???" represent the unconfirmed ones, and those are my guesses.





Accel:

Nova Grappler

Tachikaze

Aqua Force

Pale Moon

Murakumo

??? Neo Nectar

??? Gold Paladin

??? Nubatama





I have a good feeling Neo Nectar will be Accel, as Musketeers are apparently prominent in the manga, and Accel would fit the aggressive nature of that subclan. Also, Neo Nectar often enabled multiple attacks in some way, shape or form, even back when multiple attacks were more scarce (see Maiden of Trailing Rose ).





Gold Paladin have been quite fast and aggressive in the past, and Accel would help differentiate the clan from the other paladin clans, who are confirmed to be Force.





Nubatama is harder to categorise in my opinion; none of the Gifts jump out at me, but Nubatama does usually try and close the game quickly, as they usually do not have enough draw power to sustain a long game. As the clan usually wants to simplify the game state by reducing the guarding options of the opponent, Accel would be a good match for Nubatama.





Force:

Royal Paladin

Kagero

Spike Brothers

Dimension Police

Shadow Paladin

??? Gear Chronicle

??? Great Nature

??? Genesis

??? Narukami





Gear Chronicle is usually more midrange, being slower to start, but having a good balance of offence and defence. They would utilise Force well, as they could take advantage of a RC Force marker with time leap effects, or place a marker on VC and use one of their many Vanguard focused abilities, like restanding or guard restrict.





Force would fit Great Nature well, as the clan is all about buffing their Rearguards to huge numbers, and their keyword, Success, encouraged that too.





Genesis have often had very Vanguard and/or Combo reliant strategies, with many of their Rearguards existing just to fuel soul for the their Vanguard's abilities; Force supports these strategies, so I feel confident Genesis will use Force.





Narukami, similar to Kagero, usually wins through attrition, prioritising the reduction of their opponent's resources. Force is useful for this kind of strategy, as you can keep stacking multiple markers on the same circle to gain value over time, and unlike Accel, requires less field investment. I'm less confident of this guess, as Bushiroad may try and use this opportunity to differentiate the clans; it would be cool of Narukami had a different Gift to Kagero, to avoid the two clans being too similar, but I think Force would suit them the best.





Protect:

Oracle Think Tank

Megacolony

Granblue

Dark Irregulars

??? Bermuda

??? Link Joker

??? Angel Feather





I'm pretty confident with all three of these being Protect, as they all lean more towards defence and control. Drawing cards is a staple part of Bermuda's clan identity, and Angel Feather are well known for augmenting their units on the opponent's turn for defensive plays. Protect would help solidify these defensive strategies.
