Target 1 "Witchcrafter" monster in your GY; Special Summon it. During your End Phase, if you control a "Witchcrafter" monster, while this card is in your GY: You can add this card to your hand. You can only use 1 "Witchcrafter Holiday" effect per turn, and only once that turn.
Well they did the exact same thing to dragunity divine lance just because trunade.
You see, they want people to run judgement force box 3 times, as lightsworn engine is kinda fit in almost every graveyard related deck. It is their gold mine, so i believe they will keep doing this for quite a long time.
Because they supposed lightsworn engine would be used in lightsworn decks. Not IN EVERY SINGLE DECK that has acess to graveyard cards. Just limit 2-3 lightsworn engine cards and the end. Old Yugioh players may still remember a time when Charge of Light Brigade, Judgment dragon, Solar Rechrarge and Lumina were ALL in the limited - semilited list in TCG. There were a BIG problem back then, LIKE NOW.
This card actually work just fine even with a single copy, as each of the effect only work once per turn.
The problem lies in the charge of the light brigade, as usual.
Once per turn? Nope!
Any cons? Nope!
