Bloodywood - Spellcasters summoning their armies to wage war

 

Between the dense trees of the Bloodywood, wizards can find summoning circles of all kinds.

As we are talking about "Duel" here, of course they battle for control of these circles.

Each battlesite allows the wizards to summon all kinds of ferocious animals, elementals, spirits, demons - whatever his creativity allows - to wage war over the site for them ...

This is just a core idea for a game à la the M:TG 

Each player starts off with one wizard on the battlefield. He then summons his forces onto the battlefield, one by one, sacrificing minor critters to summon greater ones...

Mechanics I'll have to wrap my mind around ...
