youtube video - Witchcrafter budget pure - post ETCO 05|2020
The archtype it self have his own interesting mechanic.
You special summon the higher lvl (boss-)monsters/masters by tributing the low lvl students in addition of discarding a spellcard.
They cost seems to be high, but don't worry, the discarded spellcards, you haven't activated the same turn, will come back from the graveyard to your hand or direct on the field. You also have multiple layer of protection, negation- and destruction- effect, removal and recovery options.
This specific profile don't use "Pod of Extravagance" and "Magician's Souls" wich other build prefers, cause of budget reasons.
The Deck performce very well without them and have a good consistentcy by it self. Beside the already mentioned spellcard recycling mechanic, i built in much drawcards. Together with "Spell Chonicle" and the new trap "Witchcrafter Patronus" you can generate a big card advantage, especially in the lategame.
