like the move-set name says, all grass type attacks besides toxic, which is poison. Use leech seed first then toxic, depending on if the enemy can absorb the attack... leech seed does not effect grass types and toxic does not effect poison or steel types. Then use either synthisis or giga drain depending on how much damage you have or will receive. With leftovers you can use giga drain more often then synthisis and with stealth rock in effect stalling gets easier, because they'll either switch out with toxic on them or die off faster then you take damage.
