oh and by the way Arum, that card is insanely OP i mean i imagine that you thought the ability would be a disadvantage or something but its also a bad for your opponent so it balances out evenly, furthermore in a rainbow this could be used to your advantage, if you had 0 cards you could use this and take your opponents cards and then use them (you could even use this outside of a rainbow) and then you have the insane stats, in any case this card could work fairly well if you lowered the cost and made it a spell, hope you consider this.
Well the only problem i see is that it is slightly under cost. I can easily make it 14 for the first and 15/16 for the second. Would that do? Oh and you do not ''Keep'' your opponents cards, you only use their hand meaning you cannot get ''more cards'' thus making it so that you will lose cards as well. Oh and if you cannot draw anymore cards, i believe you die.
I dont think you understood me, i meant that if you had no cards in your hand and your opponent did and you used this you could then use their cards to your advantage if you were using a rainbow, this would then completely change the situation to your advantage, i dont quite see how decking is put int this and furthermore you said that you still draw cards from your deck so what did you mean by 'you cant get more cards'?
You only switch hands for a set amount of turns so its kinda like precognition. And if you had no cards in your hand then you wouln't be able to play this card. And you draw from your deck meaning if you had no cards in your deck then you would lose. On a side-note it would not ''COMPLETELY change it to your advantage, since you may not have the requirements.
P.S. The cards are switched back meaning if you had this card and you switched, you still would get no cards in your hand even after the switch-back.
