Splinterlands Day 15: Silver 2 League in 1 Day with 1 card in rent

I've changed daily quest from Earth to Water. By my opinion it is most difficult to complete quests for Earth summoners with starter cards only. Other colors/rules works much better than Earth.

Especially water is one of the best.

So, it is a good time to advance in league. I have water quest and 879 rating - let's try to get more.

To advance in league I've rented CREEPING OOZE (2 DEC/day) and PHANTOM OF THE ABYSS (98 DEC/day) cards. I prefer to use RULER OF THE SEAS to play with water cards, but it is too expensive to rent. PHANTOM OF THE ABYSS is less expensive and have 6 speed plus flying & dodge abilities - it is fun to watch when enemy mosters miss this targed. So I was able to complete the quest without any losses but +20% win streak:

And here is the quest reward (Another one [useless] legendary potion!):

Then I continue to level up and was successful to reach Silver 2 league (1300+ rating) in several hours of playing:

Please note I use "I need power" bot who delegates collection power for free for 5 minutes to achive league correspondig to game rating.
