The typical play for "Ashened" involves getting Obsidim to the field and "Veidos" in hand through various means, such as the Spell Card "Awakening of Veidos", followed by using the effect of "Veidos" to destroy any card in the Field Zone and Summon itself to the opponent's field, destroying Obsidim to activate its effect to Special Summon any "Ashened" monster from the Deck as well as the effect of "Veidos" to add to hand or Set an "Ashened" Continuous Trap Card from your Deck
As the monsters need to be face-up for the effect to activate and said effect Special Summons more "Krawler" monsters face-down, this provides an incentive for the controller to first flip them face-up in order to utilize the Flip effects, then have the opponent remove them with a card effect in order to make full use of both effects
