Going through some MID common/uncommon and found this guy. White on one side and has the normal MTG back on the other.

First time putting in a shed, a resin 4x6. Building a small foundation to level out after about 4 feet it slopes off so building a retaining wall out of 4x4 to backfill with gravel, sand, pavers.

Will be 2 stacked on the long end and 1 for the shorter sides, connecting this which way is best for strength and longevity of the foundation? Should the short ends overlap as pictured and be lag bolted in there or should the long end be full length and short ends bolted in from the front.
