I enjoy both T1 and T2 Tourneys over EFC by a long shot.
I’m more of a ‘gimmick deck’ player, so I enjoy using ‘less popular’ combinations of cards just to see how well it performs. But in EFC, it can take more than 3 wins to recover from 1 loss. Which is absolutely absurd, and just makes the entire mode stressful to me. In tourney, I can lose every single game, and at least still gain some reward.
But I admit, EFC rewards are better if you play long term.
Tourney is better for players with limited cards and clintz. EFC requires a large pool of expensive cards to enable switching one's deck to keep up with the shifting meta. A good way to build that pool is through Tourneys.
