Issues with a Lara Croft deck

Last year, I picked up the [[Lara Croft]] secret lair, and was recently able to finally start brewing her. However, I've run into a problem that I'm hoping the hive mind can help with.

This is my [current list](https://archidekt.com/decks/7063620/lara_crofts_adventures). I built a rather straightforward Legendary Artifact based deck with a bunch of [[Windfall]] style effects in order to fill up my graveyard so that Lara can Exile the legendaries and I can replay them later on.

However, in playtesting, I've noticed that the deck runs out of steam very quickly and I'm not exactly sure why. I either don't have anything to really do for the first few turns or I hit all my ramp cards, drop Lara with an equipment or two, and then run out of cards to play. In fact, if I don't have [[Jhoira, Weatherlight Captain]] in play, it consistently feels like I have no cards in hand, which seems weird given how many sources of card draw I tried to put in here.

Any suggestions on changes I could make? As I mentioned, consistency and gas are my two biggest issues and I'm just not sure what changes could be made to help alleviate both of them.

Thanks!
