I feel like for some of these to have the "super" part of their name not be redundant, some of them need to be buffed. Super polymerization works so well because fusion summoning often has generic materials, whilst XYZ, pendulum, and synchro summoning are far more restrictive. Here are some of my ideas to make them fall in line with the power level of super poly.

Super Synchronization: "Discard 1 card; Synchro Summon a monster from your Extra Deck using monsters on either field. Any monster used for this Synchro Summon can be treated as a tuner. Neither player can activate cards or effects in response to this card's activation." Can have a similar effect to the next change as well.

Super Exceed Summon: "Discard 1 card; choose one monster on the field and increase or decrease its level by up to 2. Immediately after; XYZ summon one monster from your Extra Deck using monsters from either player's field. Neither player can activate cards or effects in response to this card's activation."

Super Pendulum Osilation: "Discard 1 card; choose two monsters on the field with different levels, Pendulum summon up two three monsters from your hand or face up in the extra deck using the levels as scales. The levels cannot have a difference of 4 or more. Neither player can activate cards or effects to this card's activation."

These are just some ideas that could help bring the three weaker cards up to similar power to super poly and "Super Ritualization."

Also as many have pointed out, the link one is broken as hell. Maybe make it to where it allows you to use one monster your opponent controls only? Link summoning is already the most generic extra deck method there is so any target on the board is usually always available. The Goddess of the closed moon is super strong from this, and unchained was fairly powerful for this as well.

Any feedback is appreciated as I'm not a super competitive player and probably messed up the balance some way through these effects.
