.. Elemental game

Check out the info:

• ORNAMENT -> beats ICY SHARD and AMULET OF LIGHT
• SANTA'S LIST -> beats ORNAMENT and AMULET OF LIGHT
• ICY SHARD -> beats SANTA'S LIST and AMULET OF LIGHT
• AMULET OF SHADOWS -> beats ALL except AMULET OF LIGHT (can only be played once)
• AMULET OF LIGHT -> beats AMULET OF SHADOWS

It is like a game of rock-paper-scissors (ornament, list, icy shard) but with a trump (shadows) and a counter-trump (light). I think the game is random so you just have to game it.
