Forum:Future Fusion

I was just wondering. Even though Future Fusion is a continuous spell card, its effects activate one at a time and at a given condition. I'm just wondering what alternatives are there to keep the summoned fusion monster while getting rid of Future Fusion itself. By this I don't mean using cards such as Polymerization (Fuse it into the next stage) or De-fusion (Breaking up Blue-Eyes Ultimate Dragon into 3 Blue-Eyes White Dragon). I'm also curious about what it means to "negate the activation and effect of a spell card". I'm just wondering why can't you use a Magic Jammer to negate the activation and effect of a continuous spell card on time it comes into effect, not necessarily meaning the time it was first activated but when the effect is once again used like Ultimate Offering. In particular, I'm comparing this to the trap card Divine Wrath which does the same thing but to Effect Monsters. I've used Divine Wrath on Chaos Command Magician by "activating" its effect using Man-Eater Bug and then chaining Divine Wrath to Chaos Command Magician's effect. So what I am really wondering is the possibility of chaining a card like Magic Jammer to prevent the last effect of Future Fusion, when it is triggered (Say if I were use a Mystical Space Typhoon on it and then chain Magic Jammer to negate the activation and effect which would destroy the fusion monster).
