sometimes cards have really bad description of what to do such as obelisk
obelisk says when summoned no spell/traps can be activated but is that the whole turn or just to stop stuff like torrential and bottomless?
in cases of these hard to interpret effects are there any tricks to use?
other than searching the internet cuz im lazy

For obelisk.. the eff of stoping card effects lasts only at the turn before battle phase.. in other words.. Torential, bottomess, cnt stop it..
and what do u mean triks oO?

Like u know the reading card text stuff like the colons and semicolons and that all that stuff

ooh i c.. cant u be more precise lol
