Tips for using Ogre and Spud?

Recently got Ogre and Spud from a coffee and tear pack respectively, what’s the best way to use them, and on what maps? Also, do they have good synergy together?

Ogre is due to its condition naturally limited to when your heart health goes below 4000. Its not worth using it when your heart health is much above that cause it just wont do anything.
As for spud hes an efficient cheap lobber for when you need one. I find that the higher up you go the more he gets relegated to specific situations where you need a cheap lobber at that moment but for low ranks hes always a solid potential option on maps with a lot of walls.
As for synergy together not really. Theres no anti synergy either but theyre just two units with two different purposes. You can use them together and its fine but neither one helps the other in any way.

As for maps, ogre id say is limited by maps where heartrushing is very swarm based. The problem ogre tends to have is if your opponent is rushing with a lot of units, spending a lot on single target damage just doesnt work. So maps like mount rushmore, detention or maoi he tends to not work. For maps he does work, any map where you get aggroed early then throw it off he is great in. Scopposeum, and phobos tend to have early aggression that if you play decently you can fight off then hes just a big hyper efficient stat stick with no downside.
For spud, small maps with lots of walls, RCO, teen spirit etc. big wall maps you tend to prefer heavo but you can use him on big maps if you want.
