Anyone who plays the game extensively and is not blinded by the easy wins spellhai gives knows that, in its current state, Reva is far above the rest of the factions. With superior damage and reach, cycling power due to cantrips, strongest BBS, and the innate “pinging” power to make any and all artifacts virtually useless makes Reva the undisputed queen of the ladder. In my opinion, these 2 cards are the big offenders that make Reva unbearable to play againtst.
Requiring only a single mana investment, Bloodrage Mask lets the songhai player deal absurd amounts of damage while maintaining board control with spells and/or further augment the damage the enemy receives when going face. This one mana artifact single handedly forces the opposing general to stay close and attack the songhai player or use a substantial amount of resources that cost way above 1 mana to clear the artifact or simply lose the game. If the songhai general manages to equip multiple Bloodrage Mask, which is incredibly easy due to songhais draw power and the cost of the artifact, you can say goodbye to 5-10hp every turn until you manage to remove it. Good luck winning the game after that.
Possible solution for this problem would be to increasing the cost of the artifact to 2.
This is a problem card not only in spellhai but in every single aggro deck. Spelljammer makes sure that the aggro player never runs out of cards unless removed, and even if it gets removed the next turn, the aggro player will always be ahead in card advantage (and lets not forget, card draw is way more valuable to the aggro player than the midrange/control player). The fact that it is a 2/4 also makes it hard to remove in the early turns. No matter what you do, you will always lose to Spelljammer.
Possible solution: make it a 2/2 so the aggro player will be forced to play her defensively or change her effect to “both player draws a card at the end of your turn”
This is a personal opinion so feel free to disagree with me in the comments.
