do i assume you have these cards?
if you do then sweet, this is a pretty good deck i'd say or you cand test it out on the online game "kaiba Corporations"
but if your still building, i'd suggest a few battle faders and maybe a ladd or 2.
so all-in-all
side out:
spirit reaper
grand mole
put in:
2x faders (while they are still unlimited)
-krebons
-sangan
+ladd
+plaugespreader
for spells, in a monarch deck, soul exchange is a staple so you should add 1-2
- 1 smashing
+ 1 soul exchange
and the way i see your traps, it looks fine
