Attribute Releasers

The Attribute Releasers are a Seven Attributes set of Level 5 monsters with 2000 ATK and DEF. All of them have an effect that, if they were Tribute Summoned by Tributing a monster with the same Attribute, allows them to send themselves to the Graveyard to re-Summon that Tribute, then activate another effect. Then, if a Tribute Summoned Attribute Releaser is in the Graveyard, the player can banish that card to activate another effect, but you can only use one effect of an Attribute Releaser per turn, and only once per turn.

Attribute Releasers are good for re-using effects that activate when a monster is Special Summoned or Summoned in general, giving a bonus effect in the process.
