New Mellow powers to replace the old ones (because they were trash)
Sort of simple to understand, but can lead to some pretty cool tactics:

Mellow’s Meta Steal:
Mellow is able to swap or steal objects, known as Meta-stealing or Reshuffling
‎
• Max range of 10 Metres
• Anything smaller than him can be Meta-stolen
• Things bigger than him can’t be Meta-stolen BUT, things up to twice his size CAN be Shuffled
• When Shuffling with a moving object, he takes what momentum this object originally had, and the object in its new position takes Mellow’s old momentum
• Mellow has to be aware of an objects presence and its position in order to Shuffle or Meta-steal it
• It is easier for him to Shuffle/Meta-steal with an object if he can see it, rather than relying on memory
• Mellow can chose what position he’d been in when Reshuffling himself, and can do so in quick succession
• There are two types of Meta-stealing
– Meta-steal and Omni-steal
• Meta-steal = Teleporting object into his vicinity
• Omni-steal = Grappling object into his vicinity
• Omni-steal is affected by weight
• Lighter objects are dragged towards Mellow
• Heavier objects drag Mellow towards him
• It always acts as a ratio, so the object now matter how heavy will endure the force of Mellow pulling, relative to its own weight

Mellow’s Cards:
Mellow is able to generate cards to support him in battle
‎
• Made out of hardlight: essentially solid holograms
• Created through use of his wrist straps, usually flicking his wrists
• There is no limit to the amount that he can create, as long as his wrist straps have power
• Trajectory and momentum are able to be manipulated when thrown/launched using hand movements, similarly to air-bending
• Combining the two attributes above, it is possible to create a storm of cards/a large amount of wind using the cards
• These cards are also explosive, and require a click of a finger to detonate
• Mellow can swap with these cards, essentially teleporting
• He can also shoot these cards with a finger-gun, giving them long ranged potential
• Edges can be sharp or ineffective, depending on Mellow
• There are cards beneath Mellow’s boots, which allows him to perform complex maneuvers in the air (IRL Double jumps, Hovering/Gliding, Boosts in midair, Very limited flight)
• These cards can also be used as hover skates, and allows him to skim over land and water

I don’t have a picture or animation to go along with it unfortunately ):
