I am going to look at kitchen table formats for the newest set called Assassin's Creed
A deck focused on Ritual Summoning WATER monsters, particularly Gishki archetype decks, would benefit from including Gishki Shadow due to its ability to serve as the entire requirement for a Ritual Summon and its effect to search for a Gishki Ritual Spell Card
An example is the duel where Rebecca is pit against Vivian Wong
Pokemon Card Strategy: So as far as strategy goes, since Raichu is a stage 1 Pokemon card, you'll first have to get Pikachu into play (I reviewed Pikachu from this set yesterday) and then evolve Pikachu into Raichu
Since the players hand cards will be exhausted quickly and Cold-Eyed Selkie may already be in the graveyard, Sram can be of great use
Its main strategy is to activate the effects of its monsters by sending them to the graveyard or banishing them with its trap cards and gain an advantage by disrupting the opponents plays or drawing more cards
