I have changed my rental strategy in Soulkeep after I have bought 80 DEC to Rent Cards, I went to the market and to sales session and found that prices are not such high as expected and instead of renting a card for few days and losing it I will day by day buying more cards and have a good collection that will remain with me as long as I play.
Soulkeep that started recently so buying and keeping cards in it is a good strategy as with time these cards will be more rare and I can Upgrade its level as I got victory and up in League rank, and buying cards from time to time and keep playing at the end you will find yourself have what like a treasure in your assets.
Also I am waiting for tournament new rules that I want to play so these cards will be good also at the tournament so I think I have got the right decision and for this day I have bought 2 cards with about 56 DEC and I have about 23 DEC remaining in my balance so I have to buy more DEC for next buying session.
I have bought one tower and one spell, The tower was Fountain of Terror and it is level one with about 33 DEC and if you look at its stats you will find it has a singular attack type and 3 used and good attack range from 190 - 335 and fire interval 1.4 physical damage is not bad as it is from 110 to 195 buy the perfect thing about this tower is that it hits flying fiends.
The Spell will help in more than one tower as it is a rare one and I have spend 23 DEC for it and its radius is 100 and spell duration is 60 and it increase range for the tower that used in it by 120% which make it perfect with strong towers and fiends that came from more than one way.
The prices of these cards still so low so I think it is a good chance to check market from day to day as there is a difference in prices and sometimes you can find a good offer with a cheap price and the more cards you buy and got, the more your chance to eliminate fiends quickly and keep your gate safe.
