Alternate solution for 4:

Crushing Hand on Hydra

Attack Hydra with Leper Gnome

Play Flametongue Totem between Emerald Reaver and Taunt Totem

Kill Bomb Squad with Emerald Reaver

Kill Hydra with Totem

Rockbiter Weapon on Tunnel Trogg and hit face

Another solution for #1:

Magnet Skaterbot on to Spud M.E.
Spud M.E. Attack River Croc
Stampeding Kodo Attacks Spud M.E.
Play Blackwing Technician
Play Defile
Play Defile

Alternate solution for #1

1. Magnet Skaterbot on to Spud M.E.
2. Spud M.E. Attack River Croc
3. Stampeding Kodo Attacks Spud M.E.
4. Play Coin, Coin, Shieldbearer, Blackwing Technician
5. Play Twilight Drake
6. Play Defile

Also came up with a different solution for #3 involving killing the Hydra, but can't remember how I did it. 

Probably something like what I did where I popped the shield then hit the hydra with leper gnome then again with crushing hand.

For puzzle number 1. You need to cast Coin first before Twilight Drake or else it will have 1 too much health for the second defile.

Also you need to attack with the Kodo before the first Defile or else the bot will be on the wrong side and can't be attacked

3. Play Coin

4. Play Drake

5. Attack River Croc with Skaterbot

6. Attack Hot Potato with Kodo

7. Cast Defile

idk if got edited or anything, but it works perfectly, your order is wrong :D
