Can I post some ideas here? Just very simple ones that might inspire you fellow card makers, I know nothing about balancing.
(All in unupped format, just ideas)

Quantum Mortar 5

permanent

: Launch: Deals 5 (or any other balanced number) damage to your opponent
(just here so that more perms for control)
Obelisk 4

permanent

Energy Infusion 1

spell
Target permanent can use its skill once more per turn

Pandora's Box 4

: Open: Choose a non-pillar permanent. All other permanents have their skills replaced by a new random skill (if there is a cost, it costs its own element). Destroy after use.
Just my 2 cents. Pillar/non-pillar doesn't matter, they are just very rough, unrefined concepts.
