This question mostly concerns Kairi, but it also affects Beast.
For cards like Merlin and Ariel, the card text says something along the lines of: "You may discard this card from your friend area when certain conditions are met." It specifically gives you the power to discard the card, and it also says when.
Both Kairi and Beast have card texts that start of with "If you discard this card from your Friend Area...." No where in the card text does it say that you MAY discard the card. It doesn't specifically let you play it.
So is it implied that I may discard either of those cards, or do I have to have a special card like Alice or Simba or some other card that allows you to discard friends in your friend area?
This is important because this means that Alice would actually be useful if used with Kairi. If you managed to play Kairi 3 times in a row against a Dark Deck, and used Alice to discard Kairi 3 turns in a row, then your opponent will actually lose 6 dark cards instead of 3, 3 of which you get to choose. Which is helpful when going against a Dark Deck that uses cards like Wizard and Sea Neon to block out your options. Meanwhile you'd only lose 4, 3 Kairis + 1 Alice. And you weren't going to use those cards for anything besides discarding anyways.
But if Alice isn't necessary for this then never mind, because I can't imagine a good use for Alice unless you're using cards like Wendy, Jasmine or Kairi as discard fodder.
Also, if I discard either Kairi or Beast due to having used them in a battle or challenge, does that trigger their effect? I would think so, but I'd like to get other people's opinions.
Thanks.
