Tried doing the Swap Frog loop (Paying the cost for Swap Frog's 'send to hand' effect; it has been ruled that even if you only get 1 extra normal summon you can so long as Swap is going back and forth you can use him repeatedly) And it didn't work. Should go SS Swap, effect, Bounce Swap, SS Swap, bounce Swap, so on, even if you only get that single extra normal summon for a Frog monster; Paying the cost should work regardless.
