Ok, here's some tips.
1. There's a zoom-out button at the top left.
2. There's an option to send all units instead of half. The button is top left.
3. You can send units while the game is paused.
4. You *must* use "spells" for the tougher levels, often you might have to use a lot.
5. You can farm gold by picking a level and just losing it over and over.
Having problems upgrading cards in the lab. Often shows only 1 multiple of the card, while there are two, but the edit deck menu shows the correct number.
The list of cards in the lab excludes cards that are in your decks. This is done so you don't accidentally remove cards from your decks which can result in invalid decks and possible problems, confusion and even game crashes.
It would help if melee units gained hp and damage at a higher rate than ranged units. Also, monsters that evolve have a huge stat advantage over those that don't since they get 5 more levels of stat boosts. Also, Evolved range units now do much more damage than melee units generally since they attack twice whereas melee units only attack once (and often only hit 1 unit at a time). Also, could we have an increased difficulty version?
