trap hole
Yes, Trap Hole targets the monster you use it against.
Either use redstone or just dig a hole and they fall. :)
Synchro summoned is considered a special summon so Trap Hole won't have an effect on them. But try Bottomless Trap Hole or Torrential Tribute instead.
It depends on the circumstances. Generally, "Bottomless Trap Hole" will be the better card; it works on Special Summons and it removes the monster it destroys from play. However, "Trap Hole" has one advantage: the monster summoned only needs 1000 ATK to trigger it, whereas "Bottomless Trap Hole" requires at least 1500 ATK. So, it would depend upon the type of deck you planned to use or went up against, but most people would choose "Bottomless Trap Hole".
Trap Hole is not being 'chained to' the summon. Summons cannot be chained to. What is happening is that Prime Material Dragon is being successfully summoned (ie, not negated) then Trap Hole is being used in response. Because of that, it is perfectly fine for Prime Material Dragon to chain his effect to Trap Hole.
venus fly trap
no.
Bottomless Trap Hole does not target, so Tyrant Dragon is unable to negate it.
Bottomless Trap Hole does not target due to the way it can remove multiple monsters. If Bottomless Trap Hole is activated, then Stardust Dragon can be used against it, even if Bottomless Trap Hole was activated in response to Stardust Dragon's own summon.
No. Trap Hole works only when a monster is Summoned or Flipped.
if you use trap hole when your opponent summons it, the monster is destroyed and is unable to destroy umi. So yes, you can use trap hole before he destroys everything heh.
