Duel Links, and how you can get them in the game
Ive liked this version the most so far, it turns out Wrenn and Six and Teferi, Time Raveler are just great cards and they make your deck feel more powerful
In his base form, Jecht has Menace (he must be blocked by two or more creatures), and whenever he deals combat damage to a player, you can exile the card to return it to the battlefield transformed, on its other side
That gives you access to some of the most important blue Duals, a strong spread of playable copies, and a few cleaner collector options as well
Top chase cards include Mega Gardevoir ex #92, Mega Gardevoir ex #87, Mega Gardevoir ex #78, Mega Latias ex #88, Mega Kangaskhan ex #89, Mega Latias ex #79
The ramp from this will help towards your general theme but it is not good ramp
