Stassy, be advised that in Manalink there are only few types of supported tokens per each card, basically the normal ones (the ones on the Planeswalker, for example) and the special ones, which are of diffrent form depending on which card they are (Spore counters, for example).
Through coding, I've managed to support +1/+1, -1/-1, Time and Doom counters, all the other types are simulated, so you won't never be able to put a
Charge counter on an artifact which has already special counters for another use, like
Time Bomb.
Besides this,
Energy Chamber add ONLY charge counters and +1/+1 counters, so the interaction with
Shield Sphere is perfect
