Play raptite at 2
You only need one level 8 fossil and 2 time stream (the fossil extra deck ratios I find ideal are 1 skullgar, 1 skull bone, 1 skull knight, and 1 level 8 fossil your pick)
You can totally play 3 orphys scorpio and 1 darlainitan cobra alongside leviatiar to search fossil fusion and have a banish summon but it’s optional.
Play a link 4 because you usually clog up your field so you need to clear space sometimes.
