Topps [1978-present] card run

I finally went through the cards I had for all 30 MLB teams and listed them in a Google Sheets file - this projects seems to be a little tedious because I have to try and make a wantlist for cards I may not be interested in chasing after at the moment, though I do want a showcase of Topps cards for each of the current MLB teams.

The goal is to find a player's card for each team, for each of the years - anything highlighted in red means I need the particular card, anything listed in black is the card I already for the team/year and any blank spaces are spots I still have to figure out with regards to selecting a card.

For whatever reason, I chose 1978 as the starting year for this project since I figure that is already at least 37 years worth of cardboard to pore over - even if I'm not going all the way back through the old-school/vintage Topps years.

While 1978 is the starting point, the plan is find cards for the present year going forward - for as long as I have this itch for this particular project.

One rule for this project is not having a player represented more than three times - as much as I'd like certain players from particular teams represented as much as possible, I want a variety of different players.

Another rule [I may actually about to break starting from 2015] is only using cards from flagship Topps sets - I actually found some 'stragglers' that were part of update sets that I removed.

However, I'm missing a 2015 Houston Astros card and while I can fill it with a random Astros card - I think a 2015 Topps Update Carlos Correa would fit in perfectly.
