Say I have a Subterra Leo (base Gs) vs a Pyrus Leo on opponents Leo gate, would the calculation be 400•2 {400+400} (gate to Leo) = 800 then,
800 • [2(canyon) • 2(gate to canyon)] = 3200
or
800 + [400(canyon) • 2(gate to canyon)] = 1600
My guess is 1600, but not 100% sure
Also, what would happen if there were multiple opponents on the card, Subterra Leo vs Pyrus Leo and Aquos Leo
