it’ll cost you several replaces per game though 
- you’re forced to replace all the second replicant you draw
- the third replicant is a brick
- you risk getting a replicant if you replace something else (it happens, a lot)
- you’re giving up hand for
and its value as a deck thinner is gone once you play mirrorim on it. and don’t even get me started with how bad of a P2 opener replicant is. you also have to consider how sun wisp can let you topdeck game-saving cards like holy immolation, and play it immediately, whereas using replicant does not increase the number of hand cycles.
unless you’re using it for hand-size synergy(theobule, the high hand) or taking advantage of the mech tribal synergy(metaltooth-chakram, oakenheart, silver, project omega), I see no reason to play this minion.
p.s. sry man, i’ve played replicant for so long, and i’ve become way too familiar when replicant causes my downfall. on a meme note, consider making a variant that has magnetize and project omega. I mean, your deck is built for it already.
pss: careful with double mechazor. idk if you know already, but mechazor switches sides if you put another one on the board.
