If it's Tier 2 then it means it can take you to KOG during the first 3-5 days of the new season.
Totally worthy if you are a fan of Blue-Eyes archtypes; on the other hand, they can't just simply make it stronger, remember that some folks miight actually say the game is P2W and that's not true at all.
b/c UR cards are the core of each archetype deck and gems are hard to farm.
also, this blue-eyes deck is Tier 1~2. it has potential of OTK.
1st hand experienced, opponent destroy my monster and wipe out my backrow with card effects; special summon blue-eyes for OTK. (opponent go 2nd with with total 4500 damage deal)
