The 'magus' idea you mentioned gave me the idea of a series...
![Life :life](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/life18x18.png)
magus that perhaps heals you for every creature played.
![Fire :fire](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/fire18x18.png)
magus that buffs the attack power of any friendly creature summoned.
![Time :time](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/time18x18.png)
magus that affects the opponent, delaying their creatures.
![Darkness :darkness](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/darkness18x18.png)
magus that weakens the attack power of any enemy creatures played.
![Earth :earth](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/earth18x18.png)
magus that boosts the HP of any friendly creature played.
![Death :death](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/death18x18.png)
magus that reduces the Max HP of any enemy creature played.
![Aether :aether](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/aether18x18.png)
magus might require a quanta upkeep due to the first power that comes to mind, granting immortality to any creature played.
![Air :air](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/air18x18.png)
magus could grant the passive 'airborne' to friendly creature played.
![Entropy :entropy](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/entropy18x18.png)
magus might scramble a creature's skill cost, making it cost a random elemental quanta, including rainbow.
![Gravity :gravity](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/gravity18x18.png)
magus could grant momentum to friendly creatures, at a quanta upkeep price.
![Light :light](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/light18x18.png)
magus either grants biolumence, or perhaps heals all creatures when a creature is played.
![Water :water](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/water18x18.png)
magus could 'refund' you 1 quanta of that creature's element when played, essentially cutting down on the cost of summoning creatures, in a sense.
quanta upkeep seems to also be a potential balancing factor, and this list probably could more or less be straight converted into permanent auras.
Yet another idea, one I kinda like, is this effect as a spell, that provides this buff to the next creature summoned. I propose that the permanent, creature, and spell buff ideas be appropriately scattered throughout the elements, so for example,
![Aether :aether](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/aether18x18.png)
's effect becomes a spell, alongside quintessance, but working instantly, while
![Entropy :entropy](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/entropy18x18.png)
's effect, due to it's situational nature, be a permanent.
Any ideas you'd like to add to this list OldTrees?
