The Cards Resource

[daemoth]

Archetype are basically a synergy or combo that you exploit through many cards in your decks. For example, in a burn deck, the goal is do direct damage with spells and generally without attacking. Theres a card that deal 300 dmg each time a spell or trap card deals direct dmg, so every card you play deal more damage.
Its not completly necesseray if your making the cards for fun. But the synergy could just be that the deck is summoning creature of the "Ressource" type. The "Ressource - Mods" creature could get stronger for each "Ressource-Member" in the graveyard or in-play. There could be spell cards that affect only "Ressource" creature and things like that.
For example:

Ressource Mod - Dazz - Level 8 - Faerie type - Atk 2500 - Def 2000
Sacrifice a "Ressource Member" to negate the effect of target spell or trap.

Ban Hammer - Spell Equip - Can only be equipped to a "Ressource Mod" creature. Equipped Creature get +1000 Atk.

Ressource Member -Add Bot - Creature - Level 2 - Atk 1400 - Def 500 - At the start of your turn, if there no "Ressource - Mod" into play and "Add-Bot" is in your graveyard, special summon "AddBot" into play in Attack pos.
