The scareclaw engine is very consistent. It uses one card combos and can easily OTK your opponent using tri-heart, or set up a decent board by using cards like baronne de fleur and scareclaw sclash.
The adventure engine does not conflict with the deck at all, since you only use your normal summon to make scareclaw light-heart. This engine also helps to activate the additional effects of scareclaw cards by having more defense position monsters.
The kashtira engine allows this deck to be more consistent by searching out scareclaw kashtira. Additionally, kashtira fenrir can be used as an interruption for your opponent or extra material for link summoning.
This deck also makes use of triple tactics thrust to be able to search reinforcement of the army, rite of aramesir, or terraforming, allowing access to any one of the three engines.
Overall this deck combines the three engines of scareclaw adventure and kashtira into a deck that functions very well and can easily compete with today's meta.
