this could be OP as the first version of phase dragon, dejavu means basically parallel universe which takes one turn to actually happen, which is weaker but not much. The deck with 18x Time Towers 6x Sillurian dragon and 6x time rune (upgraded) should be tested ( maybe throw in 3 turtle shield instead TTs) (actually it may not be THAT fast as speed bow with lucky draws, but it CAN rewind with extra quanta and has reliable quanta to actually draw and cast a shield)
