Could obelisk the tormentor work in a synchro warrior deck and you mean the playable version of obelisk is it good decent or bad card?

Answer 1

The playable version of obelisk is really good, as it is almost invincible. In a serious tournament, players won't be able to destroy it with bottomless, torrential tribute, gyzarus, DAD.... Not only that but at the cost of 2 monsters (they can be tokens, like scapegoat or fluffy tokens) You wipe out your opponents field.

In a warrior snchro deck, it could work better than in other decks (but it would still work better in a monarch deck or in a deck that focuses on tributes) because they usually have 3 copies of ''the inmortal bushi'' which can be revived at your standby phase and then be sacrificed for oblisk. For the two tributes for Obelisk's effect, you can use marauding captain, which summons another guy, and that makes two.

Conclusion: It's a good card as long as it is placed in the right deck, in a warrior synchro (you can use some x-sabers for that, I recomend you) I would give it the same importance as any tuner.

106me ADDS: I was researching on this and I think it would most certainly work. Although I was taking too much time on this (because there are apparently 2 types of this card) and I was beaten to the answer.
