hehe but, anyways the Odin card is the best to lvl up to the max so with the ark and the nimph card, i had 2 odin card one pointing to all right directions and one pointing to all left directions and the third Odin card pointing to all directions that was the hardest to get, a nimph pointing to all right directions and to no high and up directions and a Ark Card pointing to all directions and i mean all my cards with maximum lvl so in the end it was kinda boring cuz i just had to play with the "card bosses " on memoria and they were no match for me, resuming try to use this kind of deck .
