With Toad's ability, would I have to discard a Physical card to be able to activate the "if he would become stunned, return him to his owner's hand" ability?

No.

Yes you would it is part of the payment effect of toad,

Discard a Physical card >>> Toad gets +2 ATK and has flight this turn. If Toad would become stunned this turn, instead, you may return him to your hand

It is clearly part of the gets +2 atk and has flight THIS TURN, If he would become stunned THIS TURN, instead, ...


Yes you have to discard a physical card for toad to bounce back to your hand.

Errr... I beg to feel otherwise. If there is really a need for the discard for Toad to bounce back, wouldn't the text be,

Discard a Physical card >>> Toad gets +2 ATK and has flight this turn AND IF Toad would become stunned this turn, instead, you may return him to your hand?

The full stop IMO, stops the payment effect. I may be wrong.

Everharm is correct. If a character has two distinct powers, they will be separated by a paragraph break; there's no limit on the number of sentences a power can have.

Toad has just one power.

Ok Lesson learnt. Thanks.
