I have noticed that many black-based control decks do not deploy four in the maindeck due to the life loss attached
Themed booster sets, like Mythical Island or Triumphant Light, are typically smaller sets with fewer cards compared to larger sets like Genetic Apex or Space-Time Smackdown
(This was the case even before the Master Rules April 1st 2020 Revision.) Play style[edit] Trap Monsters, whether as members of a distinct archetype (such as "Golden Land" Continuous Trap Cards) or simply generic cards (such as "Statue of Anguish Pattern"), form a slow control-based strategy that attempts to maximize card advantage or some form of utility from each Trap Monster Summoned: whether the individual Trap has its own effect on Summon, or another card, such as "Anguish Pattern", generates support advantage and/or removal
Basically, its hard to kill, and works well in decks that enjoy dealing damage with spells
