[EFFECT] Send the top 3 cards of your Deck to the GY, then, you can choose 1 Fusion or 1 Field Spell Card in your GY and add it to the hand, also, during this turn, monsters you control cannot attack except Wyrm monsters
My suggestion would be to craft SR cards that you need multiple copies for the Deck

Side Note: the reason why I chose to only run 2 Swallow's Slashes instead of 3 was because a) I'd found that 45 was a good deck size, with an 85% chance of opening with a play that would lead into the minimum of Fraulein or Samuraisaga, so to add a third copy would mean either dropping Trinities or bumping up to 50 b) Swallow's Slash requires a Shiranui monster in your deck to be banished, so while running multiple copies would be good, they would typically lose their usefulness as the duel would go on due to not always having Shiranuis in the deck to be able to resolve it
