Ra farming decks don't mind the AI attacking into this card.
But the Aromage Ra variant does not need this card (since it has Jasmine), while Cloudian Ra variant much prefer having 3 Cloudian (Acid, Cirro, Altus) on the field.
AS far as i know. It says I can use 1 Tuner + 1 non-tuner which i take to mean a normal monster. In this particular case it says as a quick effect the Fist monster may act as the tuner tribute.
No, he is not affected by any spell card. Let us say your opponent has wonder ballons with 2 counters on it, when you summon silent swordsman Lv 5 it will have its original attack even if you opponent adds another counter to wonder ballons in its next turn.
......what?
Tributing 1 monster for a Tribute Summon isn't the issue at all.....the real issue is that it has mediocre stats for a Level 5, and it only adds a specific vanilla with its effect
Erratum in third paragraph :
Wiraqocha's effect return your card in your deck not your hand. If it's possible put mask of remnants before summoning Wiraqocha.
