For Swift Gaia the Fierce Knight, his effect allows you to SPECIAL SUMMON him from your hand if he is the only card in there. But the summon counts as a NORMAL SUMMON. Does that mean you cannot normal summon any more monsters that turn, you can use Trap Hole on him, or something else.
You got it wrong, if you use the effect, it it considered a special summon, not a normal summon, read the one from the starter deck.. if u normal summon it, then of course your opp. can trap hole it
