Staff of roots and wild pair (best friends) are both much lower cost cards that help go wide quickly. I only run one wild pair (best friends) because in the meta it has been more important to have a stronger creature to deal with the armor rather than flooding the board with weaker creatures. I have tried using 3 relics but I have found that it gets bricky when you already have a relic equipped. When I was running more of the lower cost cards I found the deck was struggling to finish games and that I would end up with an empty hand and no chance to recover from a board wipe. I have considered running lightning strike at 2. I think it will become more of a factor once the balance update is implements that will make it target the strongest creature
