Just as the title suggests, I think a winning streak ladder would be good feature that would reward players that do well with good decks, and give occasional rewards, with a lower daily cooldown. Maybe every 5-10 wins the player gets to spin the wheel (as used in tournaments) with better rewards depending on the win streak or just get some coins to use towards booster packs of their choice. If they lose, their 'energy bar' resets of course, and they can only hit the win streak checkpoints they haven't reached yet. It is up to staff in the end, but I feel this feature should have a 12 hour cooldown.
Please comment and add on to this topic to what you guys may think about this.
