Summon a high stats ritual monster as soon as possible! That is the goal of this deck. After summoning a ritual monster, attack with it and decrease your opponent's LP to 0 before it is destroyed by cards your opponent controls.
Note that ritual monsters in your hand can be tributed to summon a ritual monster. That means you will send a Crab Turtle in your hand to the graveyard to summon a Fortress Whale.
Crab Turtle's ATK is very high at 2500 and not be beaten easily.
The effect of Sonic Bird allows you to get a ritual spell from your deck.
Since this deck do not have monster removal, Crab Turtle's high ATK is the only way to beat a powerful monster your opponent controls.
