I feel like this is one of the most well-realized precon decks ever out of the box, so you dont necessarily need to change 30% of the cards straight away even if I told you to jam a few games, talk with your group about the power level you want, and then decide where you want to land on the scale between AFR Set Constructed Venture Tribal and Legacy Reanimator Combo
A Lantern player will make it so that their opponents draw lands and dead cards, using cards like Ensnaring Bridge to prevent creatures from being relevant and other lock pieces to prevent players from doing anything at all to stop their demise
Haste allows players to circumvent summoning sickness, however
If you order the stack correctly, you can even get more than one extra combat on each loop, as Isshin doubles the land untapping effect in time for you to pay for Aggravated Assault again
In the multicolored deck that is using a lot of desert lands for fixing, this ends up even fitting a cheap finisher role
In this case, one deck is Ruby/Sapphire and the other is Amber/Emerald, combinations that haven't been featured in any Starter Decks to date
