The idea with Numeron decks is to destroy your opponent in one or two turns
Firstly, they have very limited starting combos, heavily relying on opening Synthess along with DJJ
Archetypes can be a useful way to discover interesting combinations of cards that work well together, using their linked abilities to drive your decks power to summon, attack and disrupt your opponent
The answer to this question, of course, depends on your level of familiarity with the card game
If they have Ash Blossom & Joyous Spring, then you simply cant summon any other monster during that entire turn at all, rendering everything youve got useless and probably resulting in an immediate loss
change the battle position of your monster, and if you do, negate the effects of that opponent's monster until the end of this turn
