Assuming you buy stones, Ciphas. If not then changing hordes is impossible. So actually a general way to play the game is to know from start what you want to be, dueler, builder, hunter... Then pick horde, skills and abilities to match that. Diamond seem nice Arakan, but only if you plan to duel a lot. If you are a player that will focus on becoming strong and win duels they are a good choice. If on the other habd, like me, want to explore a lot of the skills and features of the game, without trying to be best at dueling, saphire with its fast regeneration and potion bonus, to recover after people attacked me fast was the way to go. I am in an emerald clan but still a saphire for that reason
