I think they should added Jinzo.For people who thinks it is overpowered,no it is no more overpowered while we have cards like e-con,super rush headlong,soul exc,sphere kuriboh,yomi ship etc.
it is overpowered, the closest one its the sorcerer of dark magic (yugi lvl 40), cannot be normal summoned and need 2 spell casters lvl 6 minimum, in our current limit of 3 monsters, kinda hard to get it out, now jinzo its lvl 6 monster, normal summoned from just 1 tribute, his effect its permanent in a meta where traps are very very used, it is VERY overpowered.
Quick play spells are used far more often than traps. The only relevant traps Jinzo stops are MW, Windstorm, and Red Eyes Spirit. This is far from a trap heavy meta, outside of Red Eyes which relies on Spirit
1 tribute card with the same atk than REBD and can negate their spirit mm, kinda OP since there are not too many meta 1 tribute mobs with same or more atk than rebd, remember that we already have spells negators as Invader of Darkness and most importantly, the Fredds (Dark Freed + Jinzo in a Mausoleom of emperor deck = unstoppable on duel links)
3 jinzo - 3 dark freed - 3 mausoleum - 2 treeborn frog - 3 enemy controler - 3 soul exchange - 2 Invader of darkness - 1 tribute to the doomed (to throw other mausoleums or frog if needed) can use Balance to get 2 monsters and 2 spell cards, worst case escenario = 2 invader of the darkness/ 2 econ, so maybe restart better, so you get mausoleum 1st hand and can summon any monster or 6* monster + SE
Even if jinzo was limited to 1 there is cards to bring back from grave and even removed e.g escape from dark D.jinzo would cripple this game and the rise of 3 e-con or super rush would be inevitable and once again boring
