Here's a handy little guy that is greatly overlooked by most players. Why? Cause he's a 1 tribute 5 Star monster with only an 1800 ATK, meaning he's not going to be staying around for too long. His effect however can really make it worth while. He is the "Jinzo" for Spell Cards. While he's on the field, no spells can be activated and all others are negated. This would put a severe hurting on most people. He's also a WIND creature so surprisingly, he can fit in with the new Harpie themed decks that give bonus' to WIND creatures (and help him survive a bit longer). Ultimately in the end, he may not survive as long as "Jinzo" would, but in a Trap heavy deck with the right support creatures, watch as he will give your opponent fits trying to get rid of him. And if he does, you can always use "Call of the Haunted" in a chain with their spell card to bring him back to the field and negate it.
Lastly, keep 2 things in mind. 1) "Spell Canceller" is still affected by any continuous spell cards on the field first before his effect can activate (so he would be turned to defense position by "Level Limit - Area B" before his effect would negate it). And 2) Unlike "Jinzo", "Spell Canceller" is not restricted so you can run up to 3 in your deck.
