8-15: Using 8 cards to reach the final evolution, doing 15 full enhancings on the way.

8 Fully enhanced base cards becomes 4 stage-2 cards (Ouroboros+).

Those 4 stage-2 cards are fully enhanced, then paired, becoming 2 stage-3 cards (Ouroboros++).

These final 2 stage-3 cards are fully enhanced, then evolved to the final stage-4 card, and that card is fully enhanced.

X-Y : X cards used, with Y full enhancings during the process.

8 Ouroboros --> 4 Ouroboros+ --> 2 Ouroboros++ --> 1 Ouruboros (Eternal Circle)
