make it like Pokemon, where you can play dregs and such, and guardians are super powerful and hard to summon, with only raid bosses being more difficult. motes of light would work like the energies in Pokemon, increasing your level so you can do more damage.Players would have to attach motes of light to their characters in order for them to use exotic weapons. weapon cards would also increase your damage but only for one attack, and grenades/ super cards could work like spells/ traps from yugioh. there could be synthesis cards to re equip weapon cards from the discard pile, and a destiny vault app spell to transfer your motes of light from one character to another, provided they are the same race (dreg-vandal-servitor/thrall-acolyte-knight ect.) and strange coin cards that allow you to reveal cards from the top of the deck untill you get to an exotic card, then add it to your hand. each player would get 200 life, with the attacking/defending system of magic, but with scaled up numbers. exotic armor cards would be equipped directly onto the player, one at a time, and would give them special skills to use once per turn (armamentarium: each grenade you activate gets a double effect, and when you use a heavy weapon you may flip a coin. if heads you may add +??? bonus damage. saint-14: activating a ward of dawn super negates all damage for this turn, as well as your oponents' next. nothing manacles: scatter grenades become unblockable ect.) Tl:Dr: yes, i think it'd work!
