Example ::
- I want to trade up to a Iron
- You need 3 leads to do so
- I have 2 leads and 1 iron
- I am not able to trade up yet because I only have 2 Leads, but I have 1 Iron
- (The Idea ) Let us use 2 leads and 1 iron to trade up to the 1 iron we want to use
Or can we down grade our higher cards to gives us lower cards - like split 1 iron into 3 leads?
If not, using 2 leads and 1 iron to = a Iron you actually want to use wouldn’t be a bad idea.
