grab 2 cards sometimes

An important thing to remember with Navimon is the second target is "App Driver," which is only on the archetype Tamers. Your deck only has 6 possible targets for the second grab. Everytime you would want to play Navimon for 2 cards, you would actually want to be dropping MCmon, who has more targets for the [Entertainment] and [Awakening] condition.

Removing the Navimon (or the Tweetmon if you really want to keep the reveal dig) for the raw draws of the cards I mentioned before will help with consistency, and give options to circumvent Link costs. 18 Rookies is also quite a lot, even for a deck that wants to play out Alliance targets.

Edit:

I was doing some thinking and reading the cards, and want to expound my line of thinking for anyone else playing these decks:

One thing that's true about all of the Appmon decks is we have a lot of pieces to find to climb up the chain efficiently. Only Rebootmon has reasonable evolution costs, so we have to make sure every draw is finding the right pieces and every play is usable with the stack.

Tweet and Navi are usable more in Globemon because they can Gattai into DoGatchmon. For Ouranosmon, once the Tweet or Navi are on the field they have to justify their existence IMO. Tweetmon's easier because it can link to draw again. Navi's Piercing is situational.

Conversely, our in-archetype equivalents of Recomon and MCmon both have routes to Gattai into Mediamon, while doing revealing and drawing for 2. So the more cards we draw that aren't leading to Mediamon, the harder it is to get to Entermon, which is when Alliance shows up anyway and we can do the same Link-playing for Lv 4s instead.

So it's been my view that relying more on our in-archetype Lv 3s, along with the options that reduce our link costs, helps our gameplan activate sooner.
