I need help with a power

[d'Jarvish]

I am attempting to make the HERO System work for Magi-Nation, a somewhat obscure CCG, and I need help with the summoning effect of the Orathan Flyer

Effect -- Summoning: When your Magi plays a Creature, he or she may use energy from Orathan Flyer to pay for the Creature. The Creature's entire energy cost must be paid by Orathan Flyer.

O and if anyone here is familiar with Magi-Nation I would love to have further suggestions on how to do Spells, Relics, and Magi (I have all the other Creatures done)

Give the creature a big Endurance Reserve. Add the Usable By Other Advantage so that the creature's summoner can use it. Add a Limitation to reflect that the END in the Reserve can only be used for Summons and only if it's the sole source of END for a particular use of a Summon.

Thanks

Another Option would be buying the Summoning power or an aid through the Critter, kinda like the army of Deamons trick evil people can do in AD&D....
