{goblinslide}can I pay more and cast more tokens? And if I have Let's say three on the bf
And pay one, do I cast three tokens?
Each {Goblinslide} on the battlefield will trigger once each, meaning you will have to pay 1 mana per trigger to get three tokens total.
But if I have only one on the bf and pay let's say 3, I summon 3 tokens?
Still the same concept, you can only pay one mana per slide trigger. So for each non creature spell, you may pay one mana per slide to make one goblin per trigger you paid mana for.
Ah thanks!
