NOTE: This deck can be more viable once the skill updates has been made.
Once Fairy's Smile of Ishizu has been update and change to recover 1000LP instead of 500 once a Fairy has been drawn, using Mausoleum of the Emperor and activating its effect of reducing 1000LP per tribute will be no problem for this deck.
Fairy's Smile If you normal draw a Fairy-Type monster card during the Draw Phase, the card is shown to the opponent and you recover 1000 Life Points.
if you dont draw mausoleum, at least you draw skelengel = 2 cards next turn
If you dont draw mausoleum and no skelengel you draw rai mei
If you dont draw mausoleum and no skelengel and no rai mei, then you are the worst luck person bcs that's half of your deck
Ishizu Ishtar is useful for PvP later. Start to collect some strong Fairy monsters.
OK I agree that this deck is not good but the reasons you gave are completely bullshit lol. 4* Ladybug and Power of Dark aren't popular atm. Dark Paladin/Magic Drain are decent but rarely used, and no one ever runs Baou Sword.
