Which card did behave improperly ?
Alesha, Who Smiles at Death

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2015/3/25: Fate Reforged,duel

What exactly should be the correct behavior/interaction ?

- If player activate Alesha, Who Smiles at Death ability and if there is no creature in player gy, game will not be stuck constantly asking for creature with power 2 or less

Are any other cards possibly affected by this bug ?
-

Also Alesha, Who Smiles at Death owned by AI when attacking is forced to pay mana even if that mana is not the required and taps 3 mana which gets rejected to mana pool at least in this case.With or without a creature in the graveyard.

A couple more bugs owned by human at least:
These have to be true only if you don't have the correct type of mana to pay:
1- Alesha, Who Smiles at Death if she attacks with a card in your gy,triggers without any mana payment and the ability resolves normally.
2- If Alesha, Who Smiles at Death attacks and you have no cards at all in gy it doesn't trigger.=correct.
2a- If Alesha, Who Smiles at Death attacks and you a non-permanent (instant/sorcery) in your gy then you are asked each time to pay a ridiculous high multicolour mana payment which is different each time.
2b- If you have any permanent card in gy then it will open automatically the gy even if the ability is optional and either choose a creature with power 2 or less to revive/attack if there is one or get stuck (as mentioned in top post) if there is no creature with power 2 or less.
