Discussion: Budget upgrades to Blue eyes Structure

The new blue eyes structure is one of the most impressive in yugiohs history. Cracking open just 3 gives any new player a decently powerful strategy out of the gate but it can only do so much by itself.

With the current best option for upgrading this deck being primite which has a lordly lode that is more expensive for 1 copy then all 3 structures it begs the question, are there any other more budget friendly upgrades for this structure.

My favorite choice is the buster blader support since the blue eyes support can easily one card combo into the full buster lock
