i played the game for like 3 weeks and collected some ur and sr but i found that i cant win vs anyone high cause i dont run a certain strategy and now i deleted my acc and made a new one so what to do with a 2000 gems how i build a strategy ?
First you need to know what deck you are going to build, it should be related to the skill you use. For example, dragon deck for Kaiba's peak performance or spellcaster&fiend or dark minsters deck so that you can use the cards effectively. Add some spell cards like Riryoku (you must be at higher stage to trade it with a card trader), equip spells, spell removal like de-spell/twister and so on.
