title: scroll of greater meteor
type: sorcery
casting cost: 3 colorless mana optional cost: add 2 colorless mana per additional target, add 1 colorless mana per additional cycle place
effect: change target basic land type in cycle: m -> f -> p -> s-> i -> m
the greater meteor shatters mountains (m) into forests of shards (f), burns away forests (f) turning them into plains (p), craters plains (p) into swamps (s), deepens the swamps (s) turning what little land remains into islands (i), boils away the water around islands (i ) leaving only a mountain (M) behind
examples of how it could work:
player turns one land into the next one in the cycle for a total cost of 3
player targets one forest initial cost 3 which would change it into a plains they pay an additional 2 to move it from plains to swamp then swamp to island total cost 5
player turns their own mountain into a forest initial cost 3 adds 2 additional targets for an additional cost of 2 each turning 2 of their opponents swamps into islands for a total casting cost of 7
or a mix of any of the above with options for increased amounts of targets and places up to the players current mana limit
