So, I decided to make some cards based on Team Universe 6 from Dragon Ball Super. Obviously, the set is incomplete. Even though this is under Experimental Cards, I tried to keep the effects close to something that would be reasonable within the current meta. Anyways, looking forward to feedback, as I update this regularly.
Edit: Added Caulfila and the Referee
When this card is normal or special summoned, it is switched to face-up defense position. Once per turn, if this card inflicts battle damage to your opponent, you may add one "Auta Magetta Technique" spell or trap card from your deck to your hand.
You take no battle damage in battles involving this card. Once per turn, if this monster would be destroyed by battle, it is not destroyed.
If your opponent controls a monster with an attack greater than this card's attack by 1000 or more, you may add one "Transformation" spell card from your deck to your hand.
This card cannot be normal summoned or set. Must first be special summoned by the effect of "Transformation." This card's name is also treated as "Team Universe 6: Cabba." When this card is special summoned, select one face-up monster your opponent controls. Its attack points are reduced to 1000, and your opponent takes damage equal to the amount of attack points lost.
If you control a face-up "Cabba" monster you may add one "Transform" spell card from your deck to your hand. This effect can only be activated once per turn.
This card cannot be set. If this card is switched to defense position, it is destroyed. Once per turn, if this card would be destroyed by battle, it is not destroyed. If this card battles a monster while in face-up attack position, you can place one Secret Poison Counter on that monster at the end of the Damage Step (max.1). A monster with a Secret Poison counter is destroyed during the end phase, and your opponent takes 500 points of damage.
This cards attacks cannot be negated. This card cannot attack your opponent directly. When this card destroys a monster by battle and sends it to the graveyard, you may add one "Time-Skip" spell card from your deck or graveyard to your hand. You cannot activate it this turn. Your opponent takes no battle damage the turn you activate this effect.
This card cannot be normal summoned or set. This card can only be special summoned by "Time-Skip: Pure Progress" or by its own effect. This card's attacks cannot be negated. Once per turn, if this card would be destroyed by battle or by card effect, you may banish it instead. During your next standby phase after this effect was activated, you may special summon it in face-up attack position. If this card is summoned in this way, select one card your opponent controls, destroy it.
This card cannot be destroyed by battle. Once per turn, when a monster you control activates its effect, you may negate that effect, to place one "Referee Counter" on this card. (If the effect requires a cost, you must still pay that cost). Once per turn, during either player's turn: when a monster your opponent controls activates its effect, you may remove one "Referee Counter" from this card, negate that effect.
Discard a card from your hand to banish one face-up monster you control, to special summon a monster from your hand with the same name, but 1 level higher. You can only activate "Transformation" once per turn. During your standby phase, if this card is in your graveyard, you may discard a card to add it to your hand.
You can only activate this card when you have 5 "Team Universe 6" monsters with different names in your graveyard. Tribute one face-up "Team Universe 6: Hit" on your side of the field to special summon one "Team Universe 6: Awoken Hit" from your hand. You can only active one "Time-Skip, Pure Progress" card per turn.
You may only active this card when you control a face-up "Team Universe 6: Auta Magetta," and a face up "Team Universe 6" monster you control is targeted for attack. Negate the attack, and inflict 500 points of damage to your opponent's life points.
